提示: JPEG压缩分为三个部分: 1.JPEG压缩原理及算法(RGB/YCbCr,DCT/IDCT,量化,Z字型编码,用DPCM对DC/用RLE对AC编码/Huffman编码) 2.JPEG标记格式 3.JPEG图片文件的组织形式(位于SOS后的图像压缩数据是由MCU块怎样排列的,特别是使用了DRI之后) 还有许多细节问题: 1.解码过程中遇到“FF 00”当“FF”处理,否则忽略“FF” 2.进行DCT前YCbCr要减128,进行IDCT前要加128(相当于Y减128,YCbCr不需要加12

Matlab实现图像压缩与重构步骤
① 对图像进行小波分解,得到第一层分解的低频系数和高频系数。
② 保留低频系数,对高频系数进行基于神经网络的矢量量化编码,达到压缩。
③ 根据码书以w还原高频系数
④ 根据保留的低频系数和还原的高频系数重构图像

Endoscope image is a colorful image with 24 2
colors, which may bring dimension crisis while similar
match in RGB space. So a reasonable quantification
method in suitable color space should be proposed.

本文提出一种在原始视频DCT(离散余弦变换)与SVD(奇异值分解)域自适应嵌入水印的算法。算法首先将视频流分割成一个个场景,场景中的视频图像被变换到DCT-SVD域中,水印量化嵌入在最大奇异上,实现了水印盲检测。同时实验证明该算法在满足透明性要求下也满足一定的鲁棒性要求,能够抵抗低通滤波、中值滤波、椒盐噪声、高斯噪声、H.264压缩攻击以及统计攻击和帧剪切等攻击。-This paper presents an original video in the DCT (Discrete Cosine

二维图像信号的去噪步骤:
(1)二维图像信号的小波分解。选择合适的小波与恰当的分解层次N,并对待压缩的二维图像信号进行N层分解计算。
(2)对分解后的每一层高频系数,选择一个恰当的阈值,并对该层高频系数进行软阈值量化处理。
(3)二维图像信号的小波重构。用小波分解后的第N层近似(低频系数)和经过阈值量化处理后的各层细节(高频系数),对二维信号进行小波重构。-Two-dimensional image signal denoising steps: (1) two-dimensiona
