Abstract

The paper proposed a new environment matting algorithm to model the appearance of transparent object under different background. We used the frequency response to compute the relationship between the area of foreground object and background image. Moreover, the Kaczmarz method was applied to obtain more accurate weight matrices. In the experiments, we demonstrated that the algorithm can effectively improve the quality of compositing picture and has higher PSNR than the previous method. Besides, we also showed that the proposed algorithm can maintain the quality even the high threshold is set to reduce the computation time.
