Cipher-image compression by using compressive sensing and interweaving permutation
Recently, compressing cipher images by using compressive sensing (CS) has attracted a lot of attention. However, the previous CS-based works cannot provide satisfactory compression performance.

将彩色电视信号分离后,进行DPCM编码,其合成速率应是行频的倍数为34Mb/s1,为了能以三次群速率进行传输,要将34Mb/s信息流通过正码速调整提高到34368kb/s。候时抖动是码速调整的固有抖动,为了减小候时抖动並兼顾其它性能,本文设计了码速调整的帧结构,並对候时抖动进行了频谱分析。

PSNR Improvement Using Different Prediction Coding
Differential Pulse Code Modulation (DPCM) is one of the predictive coding techniques. The number of previous pixels employed in the estimate operation is referred to as the order of the predictor. Predictor using one pixel for estimation is called “first
