Description: 图像压缩主要目的是为了节省存储空间，增加传输速度。图像压缩的理想标准是信息丢失最少，压缩比例最大。不损失图像质量的压缩称为无损压缩，无损压缩不可能达到很高的压缩比；损失图像质量的压缩称为有损压缩，高的压缩比是以牺牲图像质量为代价的。压缩的实现方法是对图像重新进行编码，希望用更少的数据表示图像。-The main purpose of image compression to save storage space, increase the transmission speed. The ideal image compression standard is a minimum loss of information, the maximum compression ratio. Compression without loss of image quality is called lossless compression, lossless compression can not achieve high compression ratio loss of image quality and compression is called lossy compression, high compression ratio at the expense of image quality for the price. Compression of the image is re-encoded data that wish to use fewer images. Platform: |

Description: 基于Lossy-to-Lossless Image
Compression Based on Reversible Integer TDLT/KLT的压缩算法的matlab实现，在增加ROI编码模块，算法详细可以查看论文《Lossy-to-lossless image compression based on multiplier-less
reversible integer time domain lapped transform》。程序由main.m函数开始运行，输入参数有3个，分别是图像的文件名(该文件夹内的.raw文件)，图像的宽和高。-Lossy-to-Lossless Image Compression Based on Reversible the Integer TDLT/KLT compression algorithm matlab realize increased ROI coding module, the algorithm in detail you can view papers " Lossy-to-lossless image compression based on multiplier-less reversible integer time domain lapped transform " . Program run by the main.m function, three input parameters, the image file name (the file folder. Raw file), the width and height of the image. Platform: |
