Abstract: To provide with an effective method for non-photorealistic rendering for computer generated images with artistic appearances from 2D images motivates our work in this paper. The methods proposed in this paper are inspired by the many pieces synthesis mosaic effects. In this paper, we mainly propose the method for generating the artistic appearances based on the pieces synthesis and color tranfer technique. The block pieces can be chosen from arbitrary quantity images in the database. First, to accelerate synthesis speed, the mosaic effect can be generated based on the luminance channel. Further, we establish our method for obtaining RGB appearances taking the color transfer as the underlying basis. Therefore, the color of input image can be rendered to the final mosaic artistic effects. Experimental results show that our methods are effective and efficient.

Abstract: To provide with an effective method for non-photorealistic rendering for computer generated images with halftoning artistic appearances from 2D images motivates our work in this paper. The methods proposed in this paper are inspired by improved error diffusion method and image enhancement, and the whole diffusion algorithm is based on the average threshold. Firstly, source image should be transferred to the gray image. Then, error diffusion, spread component and parameter confirming can be used to obtain more details. Experimental results show that the proposed method can simulate the halftoning effect in real time, and blemishes of the results can be eliminated.

Abstract: To provide with an effective method for non-photorealistic rendering for computer generated images with sketch artistic appearances from 2D images motivates our work in this paper. The character of lines, details in the source image can be smoothed by the technique of guided filter, and then the abstract smooth appearance of the image can be simulated. In addition, the smooth effect can be enlarged and enhanced by the technique of improved line integral convolution, so the final sketch artistic image can be obtained. Experimental results show that the proposed method can simulate the real sketch effect.

Abstract: This paper presents a model for automatically generating 3D cartoon ocean water animations in real-time. The dynamic ocean water surface model is modeled by a spectral method. The cartoon rendering process is implemented by multipass on GPU: First, we code normal of ocean model and generate normal map. Next, we extract discontinuities from normal map and smooth it into edge map. Finally we combine the edge map with cartoon shading based on a projective texture mapping. Some experimental results demonstrate the prettiness and efficiency of the presented model.
