Example 1
The title display method provided by the embodiment of the present application will be described in detail below with reference to fig. 1 and 2.
Referring to fig. 1, a title display method provided in an embodiment of the present application includes the following steps:
step S110: acquiring a first image; wherein the first image is a color image including a title and a written mark.
The first image may be a color image captured by an image capture device, and the image capture device may be a digital camera or a mobile phone. The first image can be a color image obtained by shooting a paper subject text or an electronic subject text on a display device, wherein the paper subject text or the electronic subject on the display device displays a subject and a writing mark on the subject or on the periphery of the subject, and the colors of the subject and the writing mark are different. In one embodiment, the first image is an image obtained by shooting a paper theme text, where the paper theme text includes a theme and red, green, or blue writing marks on or around the theme, where a background of the paper theme text may be white, a color of the theme may be black, and the theme may be a printed font or a handwritten font; for example, the paper topic text can be a student book or problem book with printed black topics on the book or problem book and a process of answering topics with accents or marks marked with red, green, or blue pens on or around the topics when students do their questions.
Step S120: and determining the pixel point of the writing mark according to the color mark corresponding to the pixel point of the first image and a preset writing mark color mark.
The color identifier is used to identify a unique identification color, which may be represented in the form of a character, for example, a red color identifier may be R, a green color identifier may be G, a blue color identifier may be B, and the like. Because the color corresponding to the title and the writing mark is different, and the color identification corresponding to the title and the writing mark is also different, and through presetting the color identification of the writing mark, the color identification corresponding to the pixel point of the first image is compared with the preset color identification of the writing mark, and the pixel point where the writing mark is positioned can be quickly and conveniently determined.
Step S130: and in the first image, replacing the color value of the pixel point where the writing mark is located with the background color value of the first image to obtain a second image.
The color value of the pixel point where the writing mark is located is replaced by the background color value of the first image, and then the writing mark is removed to reserve the title, so that when an ink screen displays, the writing mark with different gray colors on the title or around the title can be avoided, and interference is reduced.
Step S140: and outputting the second image to an ink screen for display.
The embodiment of the application is according to the colour sign that the pixel point of first image corresponds and the sign of the mark colour of writing of predetermineeing confirm write the pixel point at mark place, and then will write the colour value replacement of the pixel point at mark place for the background colour value of first image, thereby get rid of write the mark and remain the title, and then when the ink screen shows, can avoid on the title or the peripheral mark of writing that shows different grey scale colours of title, reduce the interference.
Referring to fig. 2, in an embodiment, the determining, according to the color identifier corresponding to the pixel point of the first image and the preset writing mark color identifier in step S120, the determining the pixel point where the writing mark is located includes:
step S121: traversing color values corresponding to all pixel points in the first image; the color values include a red primary color value, a green primary color value, and a blue primary color value.
The color value corresponding to each pixel point in the first image may be represented by an RGB value, where the RGB value is data formed by different proportions of three primary colors, namely, red (Red), green (Green), and Blue (Blue), in one pixel point, that is, the RGB value is a combination of a Red primary color value, a Green primary color value, and a Blue primary color value, and the Red primary color value, the Green primary color value, and the Blue primary color value are different in combination value, and the displayed color is also different. For example, RGB (255 ) is white, (0, 255, 0) is green, and (0, 255) is blue.
Step S122: and when the value obtained by subtracting the preset threshold value from one of the primary color values is larger than the other two primary color values, determining the primary color identifier where the one of the primary color values is located as the color identifier corresponding to the pixel point.
In the field of computers, in RGB values of color values corresponding to pixel points, combinations of red, green and blue primary color values are different, and corresponding colors are also recognized to be different, but in actual use, the RGB values are different and may also be considered to be the same color, for example, for a computer, (0, 255) and (25, 112) represent different colors, but in actual use, human eyes can recognize and a person can recognize the two colors as blue, for example, in an application scene, because students have different writing strengths, paper qualities are different, pen and paper functions are different, camera parameter reasons for shooting a writing mark of a subject, and the like, when the same blue pen or different types of blue pens are used to write the mark on the subject, the corresponding RGB values are different, but in actual use, the writing marks formed in the scene can all be considered as blue and are all colors to be removed. The inventor finds out in the process of implementing the invention that: in the color value RGB value, because the RGB value is data formed by different ratios of three primary colors of Red (Red), green (Green) and Blue (Blue) in one pixel point, when one of the primary color values is still greater than the other two primary color values after subtracting a preset threshold value, it is indicated that the ratio of one of the primary color values in the pixel point is large, and then the primary color identifier where the primary color value is located can be determined as the color identifier corresponding to the pixel point, so that the practical situation can be adapted, and the color in practical use can be identified as much as possible. For example, if the red primary color of the RGB value is identified as R, the green primary color is identified as G, and the blue primary color is identified as B, the red primary color value, the green primary color value, and the blue primary color value of the RGB value of one pixel point are respectively R1, G1, and B1, the preset threshold value is M, and if B1-M > R1 and B1-M > G1, the color of the pixel point is the primary color identification B where the blue primary color value is located, that is, the color identification of the pixel point is the blue identification B. Optionally, different thresholds may be set according to different requirements, so as to achieve more accurate or looser color determination.
Step S123: and if the color identifier corresponding to the pixel point is a preset writing mark color identifier, determining the pixel point as the pixel point where the writing mark is located.
Optionally, the primary color identifiers corresponding to the red primary color value, the green primary color value, and the blue primary color value in the color values are respectively: red marks, green marks and blue marks; the color mark corresponding to the written mark comprises one or more of the following parts: red marks, green marks and blue marks; the preset color identification comprises one or more of the following: red, green and blue logos. In one embodiment, the preset color mark is identical to the color mark corresponding to the writing mark; that is, all written marks are recognized and removed. In another embodiment, the preset color of the written mark is not identical to the color identifier corresponding to the written mark, that is, the preset color mark identification is different from the color identifier corresponding to the written mark, and the preset color mark identification is one or more of the color identifiers corresponding to the written mark; at this time, a part of the written mark is recognized and removed. In some application scenarios, when students write marks on the subject, different operations may be used to write marks in different colors, for example, when drawing key points on the subject, the students may use red marks; during the process of writing the problem solving, the blue mark may be used, so that when the key point of the drawing needs to be reserved and the problem solving process is removed, the blue mark can be removed and the red mark can be reserved, that is, the preset color of the writing mark is set as the blue mark. In a specific implementation, after the first image is acquired, a selection prompt box may pop up to prompt a user to preset a writing mark color identifier.
In one embodiment, before traversing the color values corresponding to all the pixel points in the first image in step S121, the method further includes: and performing image enhancement processing on the first image. By performing image enhancement processing on the first image, the color in the first image is clearer, white is whiter, and black is blacker, so that the edge of the font and the boundary of the paper on the first image become very clear, and the background color of the paper also becomes pure white.
Optionally, the performing image enhancement processing on the first image includes: and carrying out contrast enhancement processing on the first image. By carrying out contrast enhancement processing on the first image, the color level of each pixel point in the first image can be increased, so that the written marks can be conveniently identified, and meanwhile, when the processed image is displayed on an ink screen, black and white contrast can be formed, so that the display definition is improved.
In an embodiment, in step S123, replacing, in the first image, a color value of a pixel point where the writing mark is located with a background color value of the first image to obtain a second image, where the method includes: and in the first image, acquiring the coordinates of a pixel point where the writing mark is located, and replacing the color value stored on the coordinates of the pixel point with the background color value of the first image. Through indexing the coordinates of the pixel points, the color values stored in the coordinates of the pixel points are replaced by the background color values of the first image, and therefore color replacement can be rapidly and conveniently carried out. Optionally, if the color value of the background of the first image is white (255,255,255), the color value of the coordinate of the pixel where the writing mark is located is also replaced by (255,255,255), so that the replaced writing mark is displayed on the ink screen in the same white state as the background, and further the writing mark cannot be seen on the ink screen, thereby avoiding displaying the writing mark with different gray colors on the title or around the title, and reducing interference.
