Image blurring is a very attractive feature of photography. Due to hardware constraint, it is nearly impossible for compact DC to produce such image with blurred background. In this paper, we propose a system to simulate background blurring function, which consists of two main steps. In foreground extraction step, firstly, we select meanshift based segmentation method to get over-segmented regions. Then we extract both texture and color features for each region. Furthermore, based on input

In background blurring step, to make the simulation result more natural, we calculate the distance of each pixels in the background to the foreground based on distance transform and give different blurring effect according to the distance. The experimental results show that the system can produce stratifying result and gain relatively high subjective evaluation.
