Embodiment Construction

[0041] Below, the present invention will be described in detail with reference to the accompanying drawings.

[0042] Such as figure 1 As shown, the present embodiment provides a method for generating a color sketch image, including:

[0043] The first contour image is generated by gray-scale synthesis for the input color image, and the first contour image is copied into layer A and layer B, and then the layer A is reversed and Gaussian filtered in sequence, and the layer A and layer B are synthesized to obtain a second contour image;

[0044] Gaussian filtering is performed on the input color image to obtain a blurred background image, and then the second outline image and the blurred background image are superimposed to obtain a color sketch image.

[0045] Such as figure 2 As shown, the acquisition from the input color image to the second contour image is specifically implemented by the following steps:

[0046] First, grayscale the input image, that is, the original i...

Abstract

The invention provides a colorful sketch image generating method. The colorful sketch image generating method provided by the invention comprises the following steps of: generating a first profile image by a grey synthetic method; copying the generated grey image as an image layer A and an image layer B; synthesizing the image layer A with the image layer B after carrying out color-inversing and Gaussian filter treatment on the image layer A in sequence to obtain a second profile image; carrying out Gaussian filter treatment on the input colorful image to obtain a blurred background image; and stacking the second profile image with the blurred background image to obtain the colorful sketch image. The colorful sketch image generating method provided by the invention can quickly generate colorful sketch images which are satisfying and of a hand-drawn style. Furthermore, an image stacking threshold value can be controlled by skin color detection, so that the skin color parts of the images are smooth; and the non-skin color parts of the images have clear profiles.

Description

technical field [0001] The invention relates to the technical field of using a computer to complete sketch generation, in particular to a color sketch generation method. Background technique [0002] The purpose of the sketch image is not the authenticity of the image, but the artistic characteristics of the image. The current method of sketch generation using computer has not been widely used due to its complicated processing and poor reliability. Contents of the invention [0003] Therefore, the technical problem to be solved by the present invention is: to provide a color sketch image generation method to overcome the deficiencies of the prior art, and can quickly generate a satisfactory color sketch image with a hand-painted style. [0004] Therefore, the present invention provides a method for generating a color sketch image, comprising: [0005] Step 1, adopting the method of grayscale synthesis to the input color image to generate the first contour image, copying ...
