连续色调图像无损（近无损）压缩标准Jpeg_Ls源代码(continuous tone image lossless (Near-lossless) compression standard source code Jpeg_Ls)

说明：  该程序包含两部迭代收缩阈值算法在几个方面的应用，包括图像，1范数和2范数的核心算法。(The program includes two parts of iterative shrinkage threshold algorithm in several aspects, including image, 1 norm and 2 norm core algorithm.)

电力输发电系统可靠性评估程序 解析法 系统数据在压缩包里(Power transmission and generation system reliability evaluation process analytical method system data compression bag)

RLPack is a software that gives you the power to compress your executables and dynamic link libraries in a way that keeps them small and has no effect on compressed file functionality. Further more RLPack protects your files from modification and has several protection options which help protecting your files from being changed or cracked. But compression and protection does not stop there. RLPack with iBox module can pack your dynamic link libraries and place them inside the main executable so they can not be modified. They are extracted directly to memory (or optionally to disk) hiding their presence and enabling you to keep your dynamic link libraries safe from being used by third party programs or users.

说明：  在MATLAB中循环读入多幅图像与保存多幅图像(In MATLAB in the cycle time into a number of images and preservation of multiple images)

设电文字符集D及各字符出现的概率F如下： D={a，b，c，d，e，f，g，h}（字符数n=8） F={5，29，7，8，14，23，3，11}( ) 编写完成下列功能的程序： ①构造关于F的Huffman树； ②求出并打印D总各字符的Huffman编码。 程序结构： 类型说明； 构造Huffman树的函数：Huffman_tree(H[m+1])； 求Huffman编码的函数：Huffman_code(code[n+1])； main() { 变量说明； 输入字符集D及频率F； 调用Huffman_tree(H)； 调用Huffman_code(code)； 打印编码； Y 继续？ N 停止 }
