摘要
在综合分析气象卫星云图数据高效无失真压缩方法的基础上,将二维DPCM预测器加反射型熵编码器用于各种灰度类型的气象卫星云图的无失真压缩,使压缩比与运算速度得到了较好的折中,实用效果较好.
Bases on the synthetical analyses of efficient and noiseless data compression methods of satellite image, a 2D-differential pulse code modulation (DPCM) predictor along with a reflex-type entropy encoder has been utilized to compress meteorological satellite image data for various gray scales noiselessly. Higher compression rate and faster execution speed obtained by the method have demonstrated its value to practice.
