基于huffman编解码的图像压缩算法matlab仿真

1.算法运行效果图预览 2.算法运行软件版本matlab2022a 3.算法理论概述 Huffman编码是一种用于无损数据压缩的熵编码算法。由David A. Huffman在1952年提出。该算法完全依据字符出现概率来构造异字头的平均长度最短的码字，有时称之为最佳编码，一般就叫做Huffman编码...

基于正交滤波器组的语音DPCM编解码算法matlab仿真

1.算法运行效果图预览 2.算法运行软件版本matlab2022a 3.算法理论概述在语音信号处理中，一种常见的编解码技术是差分脉冲编码调制（DPCM）。DPCM是一种无损或有损压缩技术，通过利用信号中的冗余性来减少数据传输或存储所需的比特数。在DPCM编解码中，滤波器是关键组件之一，用于对原始语...

加解密与编解码算法

A). Base64 Base64编码的思想是是采用64个基本的ASCII码字符对数据进行重新编码。它将需要编码的数据拆分成字节数组。以3个字节为一组。按顺序排列24位数据，再把这24位数据分成4组，即每组6位。再在每组的的最高位前补两个0凑足一个字节。这样就把一个3字节为一组的数据重新...
