Abstract: The image is cut into two parts, the object and background, using the Graph Cuts interactive image segmentation algorithm. Through interactive image segmentation, user segmented image into a foreground region and a background region. For background area, a variety of non-photorealistic rendering algorithm was designed, which could render the original image into artistic images with other cartoon painting, pencil drawing or painting style. For foreground region, the algorithm maintained its feathers unchanged. By merging foreground and background areas, the artistic images were obtained with variety styles. Experiments show that the algorithm designed can get the desired result for processing a certain number of images and videos.

Key words: graph cuts, bilateral filter, color quantization, pencil drawing painting, oil painting, non-photorealistic rendering
