摘　　要： 给出了同时实现两幅数字图象编码变换矩阵的定义 ,一般构造模式。证明了由编码矩阵还原原图象的正确性、唯一性并得到实现图象编码的最小上界。此方案完全采用逻辑异或运算 ,因此编码和解码速度快。编码方案具有随机性和变化的多样性。 The definition of the transformation matrix for two frame digital image coding performed at the same time and the general structural mode are given.The correctness and uniqueness of returning to the original image by means of the coding matrix are demonstrated,and the minimum upper boundary for performing imaging coding is obtained.The logical exclusion OR operation are fully applied to the scheme so coding and decoding speed is quick.The coding scheme has the advantages of randomness and variety in variation.It has a strong application value in military and bank fields,etc.
