Dimensional Color Images Of Cartoon-style Methods

Cartoon is a kind of art form which regarding plastic arts just like painting as mainly displaying means. It has already become one of the people's most favorite media propagating form nowadays. It also be applied in TV cartoon, cartoon film,game developing and other fields.In this paper, the cartoon-style rendering method for two-dimensional color image have been studied. Firstly, a number of cartoon image have been analysed then obtained the experimental data about color and regional characteristics which gave the data basis for cartoon-style rendering experiment. Then, Color-image is segmented using color vector, the regions are merged. Next, the algorithm to eliminate the unnecessary edge have been designed. Finally, the regional coloring algorithms have been designed. The experimental results show that the rendered images are closer to cartoon-style.Main contents are:(1) Color Image Segmentation. This part firstly constructed color-space model, secondly, designed two segment algorithms based the model:the threshold segmentation method and Regional growth segmentation method. Finally, Two kinds of methods have been compared segmentation effect.(2) Edge processing. The image segmentation part usually generated some unnecessary edges,so this part eliminate these unnecessary edges. The unnecessary edges usually have be divided into three kinds:isolated points, redundant edge and small pieces of region, then designed the line-filtering algorithm, the region-merging algorithm and point-filtering algorithm.(3) Regional coloring. This part mainly solve two major issues:how to determine the color to fill and how to fill regions. Because the color of region is uniform in the cartoon-image, so this article select scan-line-seed fill algorithm fills the region color.(4) System simulation. Based on vc + + 6.0 development platform this paper designed two experiments:cartoon-analysis experiment and cartoon-styled experiment, cartoon-analysis experiment achieved the color characteristics for cartoons as well as regional characteristics. cartoon-styled experiment is divided into four parts:image preprocessing, image segmentation, regional coloring and edge processing.
