基于图像匹配与补偿技术的共享屏幕实现方法

在协同工作环境下，文章给出了基于匹配的屏幕共享机制的图像补偿方法。在对图像进行分块的前提下，通过对前后两帧屏幕图像的不同块之间的匹配，决定图像数据传输的内容，让没有变化的图像块保持原样，只对图像数据中变化的部分进行传输，在客户端按接收到的图像数据对屏幕图像进行补偿。文章算法减少了图像数据传输量，解决了屏幕图像数据过大不便传输的缺点，满足了协同工作环境对实时性及图像质量的要求。

Screen Image Sharing Technology in CSCW Environment Based on Image Matching and Compensation Method

This paper gives the image matching and compensation method of screen image sharing mechanism in CSCW environment. On the premise of image segmentation, the transmission content is determined through image matching between the concerned blocks of the latter frame and the former frame. This method solves the problem of huge image data transmission because the transmission content is limited to the changed parts of screen image. With this method the system can meet the reguirements of real-time index and high quality image display requirements very well.
