Description

  The present invention relates to a graphic correction apparatus that performs correction processing of a plane graphic or a three-dimensional graphic.

  Conventionally, various methods have been proposed for easily correcting a plane figure and a three-dimensional figure. As these conventional methods, (1) a user inputs a correction line to one plane figure via an input device, and thereby a two-dimensional area is scraped or expanded based on the correction line. (2) A second method in which a user inputs correction lines to a plurality of plane figures via an input device, thereby scraping a two-dimensional region based on the correction lines or connecting a plurality of plane figures. A technique, or (3) a third technique in which a user inputs a correction line to a three-dimensional figure via an input device, thereby scraping or expanding the three-dimensional area based on the correction line. is there.

Japanese Patent Application Laid-Open No. 2004-133826 employs the first method. In Patent Document 1, the apparatus obtains the center of gravity of the region divided by the added correction line, and determines whether to scrape or expand based on the obtained center of gravity.
Japanese Patent Laid-Open No. 2004-151867 discloses a method that employs the second method. In Patent Document 2, the apparatus determines whether the added correction line is on the same plane graphic or a different plane graphic, and scrapes the area or determines the graphic depending on the relationship between the calculated graphic and the correction instruction graphic. Determine whether to connect.
Japanese Patent Laid-Open No. 2004-151867 is one that employs the third method. In Patent Document 3, the apparatus determines whether the end point of the correction line added to the three-dimensional figure is inside or outside the three-dimensional figure, and whether the area is scraped by the relationship between the obtained three-dimensional figure and the end point of the correction line. Determine whether to expand. In Patent Document 3, the first method is also employed.
According to Patent Documents 1 to 3, there is no need for the user to select whether the correction line is used for scraping or expansion (or whether two figures are connected), so that the correction work for a plane figure or a three-dimensional figure is not necessary. It becomes simple.

The graphic correction device 10a sets a graphic with no hole inside as a correction target graphic, and scrapes and expands the correction target graphic based on one input correction instruction graphic.

In the following, in order to simplify the description, the correction target graphic and the correction instruction graphic are binary images, the pixels constituting each graphic are true values (shown as white in FIG. 7 and the like), and the pixels constituting the background are false values. (Shown as black in FIG. 7 and the like).
However, the base image may be a gray scale image or a color image.

First, the configuration of the graphic correction device 10a and the graphic correction processing will be described with reference to FIGS.
As shown in FIG. 2, the graphic correction device 10 a includes a correction target graphic input unit 1, a display unit 2, a correction instruction graphic input unit 3, and a correction unit 7. The correction unit 7 includes a division unit 4, a selection unit 5, and an expansion unit 6.

The display memory 15 and the display device 17 of the graphic correction device 10 a function as the display unit 2 under the control of the CPU 11. The CPU 11 of the graphic correction device 10 a functions as the correction unit 7 by reading the program stored in the storage device 13 into the RAM of the main memory 12 and executing it.

The correction target graphic input unit 1 inputs, for example, a correction target graphic stored in the storage device 13 or the like according to an instruction given by the user via the input device such as the mouse 18 and outputs the correction target graphic to the display unit 2 and the division unit 4. To do.
The correction instruction graphic input unit 3 inputs a correction instruction graphic to be drawn on the display device 17 by the user via an input device such as a mouse 18 and outputs the correction instruction graphic to the display unit 2, the division unit 4, and the expansion unit 6. Here, it is assumed that a partial area of the correction instruction graphic overlaps with a partial area of the correction target graphic (including common pixels). If the correction instruction graphic does not overlap with the correction target graphic, the correction target graphic is not corrected.
The display unit 2 displays various input figures.

The correction unit 7 cuts off a partial area of the correction target graphic based on one correction instruction graphic and expands the partial area, thereby correcting the correction target graphic (hereinafter, “corrected graphic”). ").) Is generated.
The dividing unit 4 divides the modification target figure into a plurality of small figures (hereinafter referred to as “divided figures”) based on the correction instruction figure, and outputs the plurality of divided figures to the selection unit 5.
The selection unit 5 selects one of the plurality of input divided figures and outputs the selected divided figure (hereinafter referred to as “selected figure”) to the extension unit 6. The non-selected divided figure is a target of “shaping” and is not included in the corrected figure.
The expansion unit 6 expands the selected graphic based on the correction instruction graphic, sets the expanded selected graphic as a corrected graphic, and outputs the corrected graphic to the display unit 2.

FIG. 3 shows a procedure of graphic correction processing by the graphic correction device 10a.
First, the correction target graphic input unit 1 inputs the correction target graphic in accordance with a user instruction, and the display unit 2 (display device 17) displays the correction target graphic under the control of the CPU 11 (S101).
Next, when the user causes the display device 17 to draw a correction instruction graphic via an input device such as the mouse 18, the correction instruction graphic input unit 3 inputs the correction instruction graphic (S102).
Next, the correction unit 7 (CPU 11) corrects the correction target graphic based on the correction instruction graphic input in S102, and generates a corrected graphic (S103).
Finally, the display unit 2 (display device 17) displays the corrected figure under the control of the CPU 11 (S104).

  The user can repeat the process as necessary while viewing the correction result in S104. When the process is repeated, the graphic correction device 10a inputs the graphic after correction in S104 as the graphic to be corrected in S101.

FIG. 4 shows details of the dividing unit 4. The dividing unit 4 includes a logical negation unit 41 and a logical product unit 42.
The logical negation unit 41 inverts the truth value of the correction instruction graphic input from the correction instruction graphic input unit 3 and outputs the result to the logical product unit 42.
The logical product unit 42 calculates the logical product of the correction instruction graphic whose truth value is inverted by the logical negation unit 41 and the correction target graphic, and outputs the logical product to the selection unit 5.

  For example, when the correction instruction graphic is a curve crossing a part of the correction target graphic, the logical product calculation result output from the logical product unit 42 is a plurality of islands in which true pixels are not connected, that is, a plurality of It will contain a split figure.

FIG. 5 shows details of the selection unit 5. The selection unit 5 includes a graphic area calculation unit 51 and a maximum area graphic selection unit 52.
The graphic area calculation unit 51 receives a plurality of divided graphics output from the logical product unit 42 of the dividing unit 4, calculates the area of each divided graphic, associates the divided graphic with the area calculation result, and determines the maximum area. The data is output to the graphic selection unit 52. A known method can be used for the area calculation process. For example, the graphic area calculation unit 51 first searches all the pixels, and performs a process (labeling process) for attaching a different label to each pixel for each divided graphic. Then, the graphic area calculation unit 51 calculates the area by counting the number of pixels for each label.
Based on the area calculation result output from the graphic area calculation unit 51, the maximum area graphic selection unit 52 sets the divided graphic having the maximum area as the selected graphic and outputs the selected graphic to the expansion unit 6.

  By the processing of the selection unit 5, the user does not need to instruct which part is to be cut out and which part is to be left via an input device such as the mouse 18, and the correction work is simplified.

FIG. 6 shows details of the expansion unit 6. The expansion unit 6 includes a logical sum unit 61 and a landfill unit 62.
The logical sum unit 61 calculates the logical sum of the selected graphic, the correction instruction graphic, and the correction instruction graphic output from the maximum area graphic selection unit 52 of the selection unit 5 and outputs the logical sum to the landfill unit 62.
For example, when the correction instruction graphic is a curve that closes the inlet area of the correction target graphic (the area where the background enters the correction target graphic at an acute angle), the logical sum calculation result output from the logical sum unit 61 is the internal In the figure, there is a hole (a region in which false-value pixels that are backgrounds are connected) and all true-value pixels are connected.

  The burying unit 62 replaces the pixel of the hole existing inside the graphic as the logical sum calculation result output from the logical sum unit 61 with a true value, that is, fills the hole existing inside. A well-known method can be used for a landfill process. For example, the landfill unit 62 inverts the true / false value of the figure that is the logical sum calculation result, and labels each region where the true value pixels after the inversion are connected. Next, the landfill unit 62 calculates the area by counting the number of pixels for each label, and sets the area with the largest area as the background area. Then, the landfill unit 62 calculates a logical sum of the remaining labeled region excluding the background region and the figure that is the logical sum calculation result output from the logical sum unit 61.

  The selection condition for the background region is that instead of “region having the largest area”, “region including pixels at the end of the entire region” (however, the modification target graphic does not include pixels at the end of the entire region) It is a premise that the information is displayed as follows.) When the correction instruction figure is a closed curve such as a circle or an ellipse, the selection condition for the background area may be “external area of the closed curve”.

By the processing of the expansion unit 6, the user does not need to instruct which part is expanded and which part is not expanded via the input device such as the mouse 18, and the correction work is simplified.
Further, by the processing of the selection unit 5 and the expansion unit 6, “scraping” and “extension” of the correction target graphic are executed by one correction instruction graphic.

Next, an example of the graphic correction process performed by the graphic correction device 10a will be described with reference to FIGS.
In the example shown in FIGS. 7 and 8, the correction instruction graphic is a curve that crosses a part of the correction target graphic and closes the inlet area of the correction target graphic. Therefore, as described above, the logical product calculation result output from the logical product unit 42 of the dividing unit 4 includes a plurality of divided figures. Further, the logical sum calculation result output from the logical sum unit 61 of the expansion unit 6 is a figure in which there is a hole inside and all true values are connected.

As shown in FIG. 7, the correction target graphic 20a is a graphic having three inlets. Moreover, the correction instruction | indication figure 30a is one curve, and the edge part is not connected (it is not a closed curve).
In FIG. 8, the correction target graphic 20a is shaded, the correction instruction graphic 30a is a white line, and the positional relationship between the correction target graphic 20a and the correction instruction graphic 30a is illustrated. As shown in FIG. 8, the correction instruction graphic 30a is superimposed on a part of the correction target graphic 20a. More specifically, the correction instruction graphic 30a blocks two bays of the correction target graphic 20a and crosses the convex portions sandwiched between the two bays.

As shown in FIG. 7, the dividing unit 4 calculates a logical product 102 of the logical negation 101 of the correction instruction graphic 30a and the correction target graphic 20a. The logical product 102 includes two islands where two true pixels (white pixels in FIG. 7) are not connected, that is, two divided figures. As described above, the dividing unit 4 divides the correction target graphic 20a with the correction instruction graphic 30a as a boundary.
Next, the selection unit 5 selects the graphic with the largest area and sets it as the selected graphic 103. As for the selection figure 103, the convex part of the correction object figure 20a is shaved off. In this way, the selection unit 5 scrapes a part of the correction instruction figure 30a.
Next, the expansion unit 6 calculates a logical sum 104 of the selected graphic 103 and the correction instruction graphic 30a, performs a landfill process, and generates a corrected graphic 105. In the corrected figure 105, two bays are filled. Thus, the expansion unit 6 expands a part of the modification target graphic 20a.
In addition, the figure correction apparatus 10a may perform a smoothing process (smoothing process) on the contour portion of the corrected figure 105 as necessary.

As mentioned above, according to the figure correction apparatus 10a which concerns on 1st Embodiment, based on one correction instruction | indication figure, cutting and expansion of the correction object figure which does not have a hole are performed in combination. Thus, the user can perform intuitive graphic correction work.
In the above example, the selection unit 5 uses the divided graphic having the largest area as the selected graphic. However, the selection is not limited to this, and the user determines the selected graphic via the input device such as the mouse 18. It is also useful to configure so as to. When the correction instruction graphic is a closed curve such as a circle or an ellipse, the selection condition for the selected graphic may be “inside the closed curve”.

Moreover, although the figure to be corrected is a binary image, it is not limited to this, and if it is a multi-value image (grayscale image, color image), it may be binarized by threshold processing and distributed in two dimensions. If it is data, the distribution density may be binarized, and if it is coordinate group data indicating an outline, the area surrounded by the outline may be treated as a true value and the outside thereof may be binarized as a false value. A publicly known method can be applied to any binarization processing.
In the case of a figure expressed in three dimensions, such as a color space distribution diagram, a three-dimensional image, or a time-series contour detected from a moving image, a process that is usually performed by a person skilled in the art when displaying a three-dimensional solid is executed. The user inputs a correction instruction figure while viewing the projected image, and three-dimensionalizes the correction instruction figure in the projection direction, using the three-dimensional correction target figure and the three-dimensional correction instruction figure. What is necessary is just to perform the process similar to the process mentioned above.

The correction instruction graphic input unit 3 inputs the correction instruction graphic and outputs it to the display unit 2 and the correction unit 7.

The hole extracting unit 8 extracts holes existing in the correction target graphic and outputs the extracted holes to the hole restoring unit 9. More specifically, the hole extraction unit 8 inverts the true / false value of the correction target graphic, and labels each region where the inverted true value pixels are connected. Next, the hole extraction unit 8 calculates the area by counting the number of pixels for each label, and sets the area with the largest area as the background area. Next, the hole extraction unit 8 calculates the logical negation of the remaining region except for the background region, and outputs the calculation result to the hole restoration unit 9.
The selection condition for the background region is that instead of “region having the largest area”, “region including pixels at the end of the entire region” (however, the modification target graphic does not include pixels at the end of the entire region) It is a premise that the information is displayed as follows.) When the contour of the correction target graphic is a closed curve, the selection condition for the background region may be “external region of the contour of the correction target graphic”.

The hole restoration unit 9 restores the hole extracted by the hole extraction unit 8 into a corrected figure, and outputs the restoration result to the display unit 2. More specifically, the hole restoration unit 9 calculates a logical product of the corrected graphic output from the correction unit 7 and the hole extracted by the hole extraction unit 8, and outputs the calculation result to the display unit 2.
Through the processing of the hole extraction unit 8 and the hole restoration unit 9, it is possible to restore the holes inside the correction target graphic that are filled by the processing of the correction unit 7 and output the holes to the display unit 2.

FIG. 10 shows a procedure of graphic correction processing by the graphic correction device 10b.
First, according to a user instruction, the correction target graphic input unit 1 inputs a correction target graphic, and the display unit 2 (display device 17) displays the correction target graphic under the control of the CPU 11 (S201).
Next, when the user instructs the input of the correction instruction graphic via the input device such as the mouse 18, the correction instruction graphic input unit 3 inputs the correction instruction graphic (S202).
Next, the hole extraction unit 8 (CPU 11) extracts holes existing in the correction target graphic input in S201 (S203).
Next, the correction unit 7 (CPU 11) corrects the correction target graphic based on the correction instruction graphic input in S202, and generates a corrected graphic (S204).
Next, the hole restoration unit 9 (CPU 11) restores the hole existing in the correction target graphic extracted in S203 to the corrected graphic generated in S204 (S205).
Finally, the display unit 2 (display device 17) displays the corrected figure whose hole is restored in S205 under the control of the CPU 11 (S206).

  The user can repeat the process as necessary while viewing the correction result in S206. When the process is repeated, the graphic correction device 10b inputs the corrected graphic with the hole restored in S206 as the correction target graphic in S201.

Next, an example of the graphic correction process performed by the graphic correction device 10b will be described with reference to FIGS.
In the example shown in FIG. 11 and FIG. 12, a hole exists inside the correction target graphic. As in the first embodiment, the correction instruction graphic is a curve that crosses a part of the correction target graphic and closes the inlet area of the correction target graphic.

As shown in FIG. 11, the correction target graphic 20b is a graphic having three inlets and one hole above the inside. Moreover, the correction instruction | indication figure 30b is one curve, and the edge part is not connected (it is not a closed curve).
FIG. 12 shows the positional relationship between the correction target graphic 20b and the correction instruction graphic 30b, in which the inside of the correction target graphic 20b (however, excluding holes) is hatched and the correction instruction graphic 30b is a white line. As shown in FIG. 12, the correction instruction graphic 30b is superimposed on a part of the correction target graphic 20b. More specifically, the correction instruction graphic 30b closes the two inlets of the correction target graphic 20b and crosses the convex portion sandwiched between the two inlets.

As shown in FIG. 11, the correction unit 7 generates a corrected graphic 106 based on the correction target graphic 20b and the correction instruction graphic 30b.
Next, the hole extraction unit 8 calculates a logical negation 107 of the correction target graphic 20b, selects, for example, a region having the largest area as a background and a region excluding the background as a hole 108, and performs a logical negation of the selected hole 108. 109 is calculated and output to the hole restoration unit 9. In this way, the hole extraction unit 8 extracts holes existing in the correction target graphic 20b.
Next, the hole restoration unit 9 calculates a logical product 110 of the corrected graphic 106 generated by the correction unit 7 and the hole 109 extracted by the hole extraction unit 8 and outputs the logical product 110 to the display unit 2. In this manner, the hole restoration unit 9 restores the hole 109 that has disappeared in the corrected graphic 106.
