| 摘 要： | 为了从复杂场景中获取高质量的背景图像,提出一种基于帧间差分法和背景差分法的改进算法。将帧间差分法获得的背景图像作为视频的初始图像,将当前帧与初始图像的差值和平均差值进行比较,通过加权平均得到视频的背景图像,在背景更新时对背景图像进行选择性更新。改进算法在不同的场景中具有较强的适应能力。

| Abstract: | An improved algorithm based on frame-difference and background subtraction is pro- posed for obtaining a high-quality background image from complex scene. The current frame and foreground and background, is compared and then weight averaged in order to obtain the back- ground image, which is selectively updated while background updating. The improved algorithm has strong adaptability to different scenarios. |
