摘要
提出了差值"基础比特+溢出比特"编码方法。与霍夫曼方法相比,具有无需知道信源的统计特性,算法简便,易于实时处理,编码效率高(可达90%以上)等特点,并在成像光谱仪机上实时数据压缩中取得了良好的应用效果。
A new coding methed—Difference Base-bit plus Overflow-bit Codi- ng (DBOC) is proposed Compard with the Huffman coding,this method does not require the statistical properties of coded data, and it can be realized in real-time.Experiments show that the coding efficiency can reach over 90%.With this coding method an excellent result has been obtained in an on-board data compression system for imaging spectrometer.
