基于数学形态学视频压缩方法研究

Investigation of Mathematical Morphology in Video Compressed

将采集到的视频图像进行分割,在传统运动补偿预测编码的基础上运用了数学形态学的理论方法,通过形态变换对宏块中的不规则小块进行提取,达到滤出不规则小块的目的,再对不规则小块的大小、位置、运动矢量进行编码,该方法可以有效地减少帧间误差DFD,其效果与压缩标准MPEG-1相比,图像的压缩比和信噪比得到较好地改善。

The video gathered is parted in this article. It has used the morphology theory method of mathematics on the basis of code compensating and predicting in traditional sport to draw small irregular one in great one through the shape change and achieve the goal of leaching small irregular one, and then encode the size, position, movement vector of small irregular one. This method can decrease the DFD availably, and the compression ratio and SNR of the image are improved compared with the effect of eompress standard MPEG-1.
