Embodiment Construction

[0044] The first thing to explain is that it is assumed that the image used has three color channels, which are R (red) channel, G (green) channel, and B (blue) channel. In addition, when image processing is performed, it is performed pixel by pixel, and for each pixel, it contains three values, corresponding to three color channels, and the three values ​​are specifically: the pixel value of the R channel, The pixel value of the G channel and the pixel value of the B channel.

[0045] Such as figure 1 As shown, in the flow chart of Embodiment 1 of the generation method of colored pencil drawings of the present invention, the generation method includes:

[0046] S1. Open an N*N window centered on the current pixel point in the current color channel of the color image, wherein N is an odd number greater than 1, for example, N is 3. In addition, in this step, it should also be noted that, If at least one of the other pixels in the window except the current pixel does not exis...

Abstract

The invention discloses a method and system for generating color pencil drawings. The method for generating the color pencil drawings comprises the following steps of: S1, opening an N*N window taking a current pixel point as the center on a current color channel of a color image, wherein N is an odd number larger than 1; S2, determining an operator by comparing a pixel value of the current pixelpoint with pixel values of other pixel points in the window; S3, calculating a contour reinforcing factor according to the operator and the pixel value of the current pixel point; and (4) processing the pixel value of the current pixel point according to the contour reinforcing factor to generate the corresponding pixel value of the current pixel point of the current channel in the color pencil drawing. Through the implementation of the technical scheme of invention, the steps are simple and the realization efficiency is high.

Description

technical field [0001] The invention relates to image processing technology, in particular to a method and system for generating colored pencil drawings. Background technique [0002] Colored pencil drawing is an art form in which a pencil is used as a medium to express a scene or a scene with lines. Creating colored pencil drawings by hand requires the author to have certain art skills, so computer simulation to generate sketches has important application and entertainment value. At present, users can process photos, images or video streaming images through special software (such as Photoshop, etc.) to form the effect of colored pencil drawings, but this generation method is complicated, the overall steps of the algorithm are complicated, and the implementation efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for generating colored pencil drawings with a simple method and high efficie...
