Embodiment Construction

[0031] The present invention will be further described below in conjunction with accompanying drawing:

[0032] Such as figure 1 Shown: the present invention comprises the following steps:

[0033] (1) Input image decolorization: Convert the input image Input(x,y) to grayscale image Gray(x,y):

[0034] Gray(x,y)=0.299×Input R (x,y)+0.587×Input G (x,y)+0.114×Input B (x,y);

[0035] Where: Input R (x,y), Input G (x,y), Input B (x, y) represents the red, green and blue three-channel value of the input image Input(x, y), and (x, y) represents a certain pixel position in the input image and the grayscale image;

[0036] (2) Input image digital matting: use Poisson digital matting method for grayscale image Gray(x,y) to perform image digital matting, extract the subject in the grayscale image, and obtain the foreground image Fore(x,y) :

[0037] Fore ( x , y ) = ...

Abstract

The invention discloses a pop art style drawing method based on non-photorealistic. The method comprises the steps that an input static two-dimension image is converted into a gray level image, a Poisson digital matting method is used for conducting image segmentation, and a body in the gray level image is extracted; the gray level image is segmented in a threshold segmentation method to obtain a black image and a white image, and a filtering method is used for conducting filtering smoothness on the black image and the white image; a white area is deleted, pixel points in a black area are reserved to generate a final foreground image; images with color textures are selected to be used as texture samples, and a texture synthesis method is used for synthetizing a final background image; at last, the foreground image and the background image are fused, and a final colored pop art effect image is obtained. The pop art style drawing method based on the non-photorealistic has the advantages of more according with the aethestic standard of people, and being wide in application range, high in processing speed and good in flexibility, thereby being a beneficial supplement for non-photorealistic to simulate different artistic effects.

Description

technical field [0001] The invention relates to a computer graphics processing method, in particular to a non-realistic-based spectral art style drawing method. Background technique [0002] Non-photorealistic rendering (NPR: Non Photorealistic Rendering) is based on human perception, combines artistic painting rules and scientific technical methods, and uses computers to generate graphics with hand-painted styles such as cartoons, oil paintings, and watercolors, mainly to express graphics It plays a more and more important role in the simulation of natural artistic style, the enhancement of image information, the generation of animation, the artistic expression of data, and the fields of medicine, architecture, and education. more important role. In addition, NPR adapts to image content, ignores minor details, and effectively attracts users' attention to key or important parts; it can save a lot of manpower, material resources and time to complete the animation production ...
