Figure 2 is a block diagram of an electronic device according to an embodiment of the present invention.

Referring to FIG. 2, the electronic device 200 may include a storage unit 210 and a processor 220.

The storage unit 210 may include volatile or non-volatile recording media.

The storage unit 210 is connected to one or more processors and can store codes that, when executed by the processor 220, cause the processor 220 to control the electronic device 200.

Here, the storage unit 210 may include magnetic storage media or flash storage media, but the scope of the present invention is not limited thereto. This storage unit 210 may include internal memory and/or external memory, volatile memory such as DRAM, SRAM, or SDRAM, one time programmable ROM (OTPROM), PROM, EPROM, EEPROM, mask ROM, and flash ROM. , non-volatile memory such as NAND flash memory, or NOR flash memory, SSD. It may include a flash drive such as a compact flash (CF) card, SD card, Micro-SD card, Mini-SD card, or memory stick, or a storage device such as an HDD.

As an example, the storage unit 210 may pre-store Korean fonts, Chinese character fonts, an attribute value similarity distance table, which will be described later, and a font similarity ranking table.

The processor 220 can generally control the electronic device 200.

In particular, the processor 220 may perform a processor to recommend or provide Hangul fonts and Chinese character fonts.

As an example, the processor 220 may obtain an optimal combination of Korean stroke elements and Chinese character stroke elements.

For example, first, the processor 220 may obtain a representative Korean stroke element with high importance among the Korean stroke elements. Additionally, the processor 220 can obtain representative Hangul stroke elements with high importance among Chinese character stroke elements.

Additionally, the processor 220 may obtain font-specific attribute values for predefined Korean stroke elements and font-specific attribute values for Chinese character stroke elements. In this case, the processor 220 may generate an attribute value similarity distance table by obtaining similarity distances for font-specific attribute values for Korean stroke elements and font-specific attribute values for Chinese character stroke elements.

The processor may obtain a font similarity ranking table based on the generated attribute value similarity distance table. Here, the font similarity ranking table can be created by assigning a higher rank as the similarity distance included in the attribute value similarity distance table is smaller.

Meanwhile, the processor 220 may load the font similarity ranking reference table from the storage unit 210 and obtain the ranking similarity with the generated font similarity ranking table.

The processor 220 may determine the similarity between Korean stroke elements and Chinese character stroke elements based on the obtained rank similarity. That is, the processor 220 may select at least one set of Korean stroke elements and Chinese character stroke elements with the highest similarity (or highest suitability) based on the obtained rank similarity.

In this case, the processor 220 may provide a recommended Chinese character font or a recommended Korean font matching the pre-selected Hangul font or the pre-selected Chinese character font based on the selected set of at least one Hangul stroke element and Chinese character stroke element.

For example, assume that the pre-selected Hangul font is a batang font, and the selected set of at least one Hangul stroke element and Chinese character stroke element is a beak (Hangul stroke element) and a slant (Chinese character stroke element). In this case, the processor 220 obtains the first attribute value mapped to the batang and beak from the stroke element attribute value table containing all Hangul fonts, and the first attribute value mapped to the batang font and beak from the stroke element attribute value table containing all Chinese character fonts to all Chinese character fonts. For this purpose, a plurality of second attribute values mapped to the cross-hatching are obtained. The processor 220 may calculate the similarity distance between the first attribute value and the plurality of second attribute values and recommend the Chinese character font corresponding to the closest similarity distance as a matching font.

In the above-described embodiment of the present invention, a method of providing a matching Chinese character font for a pre-selected Hangul font has been described, but this may be equally applied to a method of providing a matching Hangul font for a pre-selected Chinese character font.

For example, assume that the pre-selected Chinese character font is Yeongmyeongjo, and the selected set of at least one Hangul stroke element and Chinese character stroke element is a beak (Hangul stroke element) - skew (Chinese stroke element).

In this case, the processor 220 obtains the third attribute value mapped to Yeongmyeongjo and slant slash from the stroke element attribute value table containing all Chinese character fonts, and all Hangul characters from the stroke element attribute value table containing all Hangul fonts. Obtain a plurality of fourth attribute values mapped to the beak for the font. The processor 220 may calculate the similarity distance between the third attribute value and the plurality of fourth attribute values and recommend the Hangul font corresponding to the closest similarity distance as a matching font.

Figure 3 shows Korean stroke elements according to an embodiment of the present invention.

The structure of Hangul or Chinese characters consists of stroke elements, skeleton, and spatial information. Among these, the stroke element represents the characteristics of the stroke shape. For example, stroke elements are composed of names derived from the movement of the brush, such as bending, ending, descending, and spiking. Font shape characteristics for judging font similarity can be defined based on stroke elements.

Examples of Hangul stroke elements include projections, beaks, bends, intersections, branches, protrusions, horizontal endings, vertical endings, spiking, downward dots, tops, and topknots.

Figure 4 shows representative Korean stroke elements according to an embodiment of the present invention.

Referring to FIG. 4, representative Korean stroke elements according to an embodiment of the present invention may include a total of seven elements: topknot, beak, branch, protrusion, bend, spout, and vertex. At least one of these representative Hangul stroke elements may be replaced with another Hangul stroke element, and may be composed of various numbers of combinations. Additionally, representative Korean stroke elements may be selected by the user or determined through deep learning based on the structure, size, texture, width, weight, direction, and shape of the stroke elements.

Figure 5 shows Chinese character stroke elements according to an embodiment of the present invention.

Because Hangul fonts and Chinese character fonts are different languages, their structure, size, texture, width, weight, direction, and shape are different. Therefore, Hangul stroke elements and Chinese character stroke elements are defined differently.

Referring to Figure 5, for example, the Chinese character stroke elements are the beginning of the horizontal line, the end of the horizontal line, the beginning of the vertical line, the end of the vertical line, the dot, the beginning of the downward stroke, the end of the downward stroke, the end of the long side stitch, and the start of the comb stroke. Part, end of comb stitch, end of long stitch, upper bend, lower bend, conclusion of comb bend, end of horizontal support, curved comb, end of long stitch, end of bent side stitch, beginning of long stitch, conclusion of bent hem, bent side stitch It may include a conclusion, the beginning of a short chimney, the end of a short chimney, and the conclusion of a comb bend.

Figure 6 shows representative stroke elements of Chinese characters according to an embodiment of the present invention.

Referring to Figure 6, representative Chinese character stroke elements according to an embodiment of the present invention include a total of 7 branches, down points, slanted strokes, the beginning of long strokes, the end of comb strokes, the ends of horizontal stems, and comb strokes. can do. At least one of these Chinese character representative stroke elements may be replaced with another Chinese character stroke element and may be composed of various numbers. Additionally, representative Chinese character stroke elements may be selected by the user or determined through deep learning based on the structure, size, texture, width, weight, direction, and shape of the stroke elements.

As an example, the above-mentioned Korean stroke elements and Chinese character stroke elements can be automatically extracted by using the Tensorflow Object Detection API and tuning and applying the Faster R-CNN model.

Meanwhile, attribute values can be set for each of the stroke elements of Hangul and Chinese characters. Here, the attribute value for the stroke element indicates the degree to which the characteristics of the stroke element stand out.

Below, the process of obtaining attribute values for Korean stroke elements will be described with reference to FIGS. 7 and 8, and the process of obtaining attribute values for Chinese character stroke elements will be described with reference to FIGS. 9 to 12.

Figure 7 shows measurement standards for attribute values for Korean stroke elements according to an embodiment of the present invention.

Referring to FIG. 7, the processor 220 determines the attribute value of the topknot based on the bending attribute of the topknot, determines the attribute value of the beak based on the beak angle of the vertical stem, and determines the attribute value of the branch based on the thickness of the stem. Determine the attribute value, judge the attribute value of the bend based on the roll and bend, judge the attribute value of the protrusion based on the conclusion and protrusion, judge the attribute of the puncture based on the sharpness of the puncture, and determine the property of the vertex. The properties of a vertex can be judged based on its shape. Here, the attribute value may be determined as 0 to 4 points, but may vary depending on the definition.

As an example, the above-mentioned attribute values can be obtained by performing deep learning to which the Faster R-CNN model is applied. Alternatively, the measurement method of FIG. 7 may be provided in the form of a survey to the general public or experts and obtained statistically.

Figure 8 shows a Korean stroke element attribute value table according to an embodiment of the present invention.

Specifically, Figure 8 is a table of attribute values of a plurality of Hangul stroke elements for a plurality of Hangul fonts. For example, the attribute value of the Korean stroke element topknot for the batang font is 4.0. Alternatively, the attribute value of the batang font for the Korean stroke element topknot is 4.0.

Figure 9 shows measurement standards for attribute values for Chinese character stroke elements according to an embodiment of the present invention. Figure 10 shows measurement standards for attribute values for Chinese character stroke elements according to another embodiment of the present invention. Figure 11 shows measurement standards for attribute values for Chinese character stroke elements according to another embodiment of the present invention.

Referring to FIG. 9, the processor 220 determines the attribute value of the bent crosshair based on the angle of the bend, determines the attribute value of the beginning of the long pointer based on the presence or absence of a beak and the angle, and determines the attribute value of the beginning of the long pointer based on the angle of the bend. Determine the attribute value of the tip of the comb based on the degree, determine the attribute value of the end of the horizontal stem based on the protrusion and shape (protrusion size) of the tip, and determine the presence or absence of protrusion and shape (protrusion length) at the ending position. Based on , you can judge the attribute value of the comb bend and chim conclusion, judge the attribute value of the branch based on the thickness of the stem and how thick or thin it is, and judge the attribute value of the Naeri point based on the shape of the Naejeom point. Here, the attribute value may be determined as 0 to 4 points, but may vary depending on the definition.

As an example, the above-mentioned attribute values can be obtained by performing deep learning to which the Faster R-CNN model is applied. Alternatively, the measurement methods of FIGS. 9 to 11 may be provided in the form of a questionnaire to the general public or experts and obtained statistically.

Figure 12 shows a Chinese character stroke element attribute value table according to an embodiment of the present invention.

Specifically, Figure 12 is a table of attribute values of a plurality of Chinese character stroke elements for a plurality of Chinese character fonts. For example, the attribute value of the Chinese character stroke element branch for Yeongmyeongjo is 2.25. Alternatively, the attribute value for the English tone for the Chinese character stroke element branch is 2.25. Here, since the attribute value may be calculated as the average of a plurality of data, it may be expressed as a number in decimal form.

Figures 13 and 14 are flowcharts of a method for providing fonts according to an embodiment of the present invention.

Referring to FIG. 13, the processor 220 includes a first attribute value table of a plurality of Hangul stroke elements for a plurality of Hangul fonts (e.g., FIG. 8) and a plurality of Chinese character fonts for a plurality of Chinese character fonts. A second attribute value table (eg, Figure 12) of Chinese character stroke elements can be obtained (S1310).

In addition, based on the first attribute value table and the second attribute value table, the processor 220 determines the attribute value between the attribute value for each Korean font for a predefined Korean character stroke element and the attribute value for each Chinese character font for a predefined Chinese character stroke element. An attribute value similarity distance table including the similarity distance can be obtained (S1320).

Referring to FIG. 15, the processor 220 uses the predefined Chinese character stroke elements corresponding to the topknot, which are predefined Hangul stroke elements, such as branch, descending dot, angled comb, start of long pointer, end of comb, and end of horizontal stem. The similarity distance (Euclidean distance) can be calculated for each of the slanted and diagonal lines.

Here, the similarity distance can be obtained based on Equation 1 below.

here, Is This is the property value of the second Korean font, Is This is the attribute value of the second Chinese character font.

Referring to FIG. 16, for example, it is assumed that the predefined Korean character stroke element is cliche, and the predefined Chinese character stroke element is assumed to be eggplant. In this case, the processor 220 sets the attribute values for each of the seven Korean fonts matching the topknot, branch, descending point, slanted line, beginning of long pointer, end of comb point, end of horizontal stem, and slant point conclusion. The similarity distance of each attribute value for the seven matching Chinese character fonts can be calculated. Through this, the processor 220 can obtain an attribute value similarity distance table for the topknot and branch sets, as shown in FIG. 17, for example.

As an example, Figure 17 is a table for topknot and branch sets. When creating a table for all sets of 7 Korean stroke elements and 7 Chinese character stroke elements, a total of 49 attribute value similarity distance tables can be obtained. there is.

Additionally, the processor 220 may obtain a font similarity ranking table based on the attribute value similarity distance table (see FIG. 17) (S1330). Here, the font similarity ranking table is matched to a set of Korean stroke elements and Chinese character stroke elements.

Specifically, the processor 220 can convert the similarity distance value included in FIG. 17 into a similarity ranking list with the Korean font, according to the principle that the shorter the Euclidean distance, the more similar it is.

As an example, a total of 49 font similarity ranking tables in Figure 18 can be obtained when creating a table for all sets of 7 Korean stroke elements and 7 Chinese character stroke elements.

The processor 220 may load the font similarity ranking reference table from the storage unit 210 . As an example, the font similarity ranking reference table may be the result of an expert evaluating the similarity between a plurality of Korean fonts and a plurality of Chinese character fonts. In this case, the font similarity ranking reference table may be the result of similarity judgment for the Korean font and Chinese character font itself without considering the Korean stroke elements and Chinese character stroke elements.

Processor 220 may obtain a rank similarity table (cosine similarity table for stroke element set, see FIG. 20) between the loaded font similarity ranking reference table (see FIG. 19) and the font similarity ranking table (see FIG. 18). There is (S1340).

Here, rank similarity can be calculated using Equation 2 below.

Here, A is the ranking value included in the font similarity ranking table for the topknot and branch sets, and B is the ranking value included in the font similarity ranking reference table.

As an example, referring to FIG. 20, the processor 220 calculates the cosine of the rank value included in the font similarity ranking table (A) for the topknot and branch set and the rank value included in the font similarity ranking reference table (B). By performing similarity calculation (Equation 2), a coin similarity of 0.7307 for the topknot and branches can be obtained.

In Figure 20, the processor 220 only calculated the cosine similarity for the topknot and branch sets (once), but the processor 220 additionally calculated the cosine similarity for other Korean stroke elements and Chinese character stroke elements (48 times). By performing this process (49 times in total), you can obtain a cosine similarity table for the stroke element set.

The processor 220 may obtain an optimal set of at least one Korean stroke element and Chinese character stroke element based on the size of the obtained rank similarity (S1350). Here, optimal can be defined as having a high degree of similarity between Korean stroke elements and Chinese character stroke elements.

Referring to FIG. 21, for example, when the processor 220 allows duplication of stroke elements in the stroke element set, branch-branch set, peak-down point set, branch-bend set, protrusion-long point set, It can be judged that there is a high degree of similarity between the bend-slash set, the protrusion-horizontal stem set, and the pinch-slash set.

Referring to FIG. 22, for example, when the processor 220 does not allow overlapping stroke elements in the stroke element set, the beak-branch set, the top-knot-down dot set, the branch-bend slash set, the protruding-long point set, It can be judged that there is a high degree of similarity between the bend-offset set, the peak-offset set, and the vertex-horizontal stem set.

For example, when duplication of stroke elements is allowed, the Korean stroke element branch has the greatest coin similarity with respect to the Chinese character stroke element branch. When stroke element duplication is not allowed, the processor 220 may determine the Chinese character stroke element branch and the Hangul stroke element branch with the second highest coin similarity as the most appropriate set to avoid duplication of Hangul stroke element branches.

Meanwhile, the processor 220 may obtain a stroke element attribute value table of all Korean fonts and a stroke element attribute value table of all Chinese character fonts (S1360). Hereinafter, it will be described in detail with reference to FIGS. 23 and 24.

Figure 23 shows the process of creating an entire Korean stroke element attribute value table according to an embodiment of the present invention.

Referring to FIG. 23, the processor 220 can perform an automatic stroke element extraction process for 13 representative Korean fonts by using the Tensorflow Object Detection API and tuning and applying the Faster R-CNN model. In this case, the processor 220 can automatically extract Hangul stroke elements such as topknot, beak, branch, protrusion, bend, pinch, and vertex.

Additionally, the processor 220 may determine Korean stroke element attribute values for the automatically extracted stroke elements by applying the Faster R-CNN model. The processor 220 can continuously apply and improve the learning results to additional Hangul fonts based on the Hangul stroke element attribute value calculation learning results to generate an entire Hangul stroke element attribute value table.

Of course, the above-described embodiment of the present invention can also be applied to generating an entire Chinese character stroke element attribute value table.

Figure 24 shows the process of creating an entire Chinese character stroke element attribute value table according to an embodiment of the present invention.

Referring to FIG. 24, the processor 220 can perform an automatic stroke element extraction process for 14 representative Chinese character fonts by using the Tensorflow Object Detection API and tuning and applying the Faster R-CNN model. In this case, the processor 220 can automatically extract Chinese character stroke elements such as branch down point, slant point, long point, slant, horizontal stem, and slant point.

Additionally, the processor 220 may determine Chinese character stroke element attribute values for the automatically extracted stroke elements by applying the Faster R-CNN model. The processor 220 may continuously apply and improve learning results to additional Chinese character fonts based on the Chinese character stroke element attribute value calculation learning results to generate an entire Chinese character stroke element attribute value table.

Referring to FIG. 25, the processor 220 can generate an entire Hangul stroke element attribute value table for additional fonts (hundreds to thousands) through the entire Hangul stroke element attribute value table generation process described above.

Additionally, referring to FIG. 26, the processor 220 can generate an entire Chinese character stroke element attribute value table for additional fonts (hundreds to thousands) through the entire Chinese character stroke element attribute value table generation process described above.

Figure 27 illustrates a font recommendation method according to an embodiment of the present invention.

According to various embodiments of the present invention described above, an optimal set of Korean stroke elements and Chinese character stroke elements were determined. For example, the processor 220 provides an optimal set of Hangul stroke elements and Chinese character stroke elements, including four types of Hangul branches and Chinese character bending guidelines, Hangul protrusion and Chinese character long guidelines, Hangul bends and Chinese character skewing, and Hangul squeaks and Chinese character skewing guidelines. Assume that you have selected .

Based on the selected set of at least one Hangul stroke element and Chinese character stroke element, the processor 220 selects a recommended Chinese character font or a recommended Hangul font that matches the pre-selected Hangul font (given Hangul font) or the pre-selected Chinese character font (given Hangul font). can be provided.

To this end, the processor 220 may obtain a similarity distance between a predefined Hangul font or a predefined Chinese character font and at least two attribute values matching at least one Hangul stroke element and a set of Chinese character stroke elements.

In this case, the processor 220 may determine the shortest Hangul font or Chinese character font among the obtained plurality of similarity distances as the recommended Chinese character font or recommended Hangul font.

As an example, the processor 220 may, in the entire Hangul stroke element attribute value table, simultaneously correspond to a pre-selected Hangul font and at least one Hangul stroke element included in the selected at least one Hangul stroke element and Chinese character stroke element set. 1 Attribute value can be obtained.

Additionally, the processor 220 may obtain a second attribute value corresponding to at least one Chinese character stroke element included in the selected at least one Korean stroke element and Chinese character stroke element set from the entire Chinese character stroke element attribute value table. .

The processor 220 may obtain the similarity distance between the first attribute value and the second attribute value using Equation 1. Here, the processor 220 may obtain an average distance when there are multiple similarity distances.

In conclusion, the processor 220 can recommend the Chinese character font when the similarity distance between the first attribute value and the second attribute value is closest as a matching font for the preselected Hangul font.

As another example, the processor 220 may, in the entire Chinese character stroke element attribute value table, simultaneously correspond to a pre-selected Chinese character font and at least one Chinese character stroke element included in the selected at least one Korean stroke element and Chinese character stroke element set. 3 Attribute values can be obtained.

In addition, the processor 220 may obtain a fourth attribute value corresponding to the selected at least one Hangul stroke element and at least one Hangul stroke element included in the Chinese character stroke element set from the entire Chinese character stroke element attribute value table. .

The processor 220 may obtain the similarity distance between the third attribute value and the fourth attribute value using Equation 1. Here, the processor 220 may obtain an average distance when there are multiple similarity distances.

In conclusion, the processor 220 can recommend the Korean font when the similarity distance between the third attribute value and the fourth attribute value is closest as a matching font for the preselected Chinese character font.

Figure 28 shows a font recommendation method according to another embodiment of the present invention.

Referring to FIG. 28, it is assumed that the processor 220 has selected three optimal sets of Hangul stroke elements and Chinese character stroke elements: Hangul branch and Chinese character skew, Hangul protrusion and Chinese character long guide, and Hangul deviate and Chinese character skew.

The processor 220 may provide a recommended Chinese character font matching a pre-selected Hangul font (given Hangul font) human script based on the selected set of at least one Hangul stroke element and Chinese character stroke element.

As an example, the processor 220 may, in the entire Hangul stroke element attribute value table, simultaneously correspond to a pre-selected Hangul font and at least one Hangul stroke element included in the selected at least one Hangul stroke element and Chinese character stroke element set. 1 Attribute value can be obtained.

For example, the first attribute value may include a total of three stroke element attribute values, a branch stroke element attribute value, a protrusion stroke element attribute value, and a bend stroke element attribute value corresponding to the human body.

Additionally, the processor 220 may obtain a second attribute value corresponding to at least one Chinese character stroke element included in the selected at least one Korean stroke element and Chinese character stroke element set from the entire Chinese character stroke element attribute value table. .

For example, the second attribute value may include a stroke element attribute value of an inclined point, a stroke element attribute value of a long pointer, and a stroke element attribute value of an oblique point corresponding to the English tone. In addition, it may include all of the stroke element attribute values of the inclined stroke, the stroke element attribute value of the long stroke, and the stroke element attribute value of the slash corresponding to Chinese character fonts other than Yeongmyeongjo.

The processor 220 may obtain the similarity distance between the first attribute value and the second attribute value using Equation 1. Here, the processor 220 may obtain an average distance when there are multiple similarity distances.
