运动补偿帧差图像的预测处理

Prediction-Processing for Motion-Compensated Frame Difference Images

针对 MCFD图像的特点提出了一种基于最小平方 (L S,L east Square)预测的处理技术 ,减少了 MCFD图像中的灰度值突变 ,灰度分布趋于平缓 ,提高了变换编码的效率 .实验结果表明 ,所提出的

A predictor was employed for a MCFD image to reduce the inherent spatial correlation in a MCFD image, and the predicion processed MCFD image is smoother than original one. This can improve the efficiency of transform coding largely. The experimental results show that DCT transform is more efficient for predicion processed MCFD images than original ones.
