本文重新讨论电视帧内编码中二维DPCM的一个老方案:预测值用序列测试图象(抽样频率10MHz)进行的计算机模拟之主观实验表明:此方案的图象质量优秀。
This article revisits an old scheme for two-dimensional DPCM in TV intra-frame coding: Subjective experiments with computer simulations of predictive values using sequential test patterns (sampling frequency 10 MHz) show that the picture quality is excellent.
