用matlab对照片进行频域变换，并进行简要分析比较DCT、DFT、WH等方式重构的图像与原始图像之间的差别，并写出报告(use matlab to perform the frequence transform and use DCT/DFT/WH to rebuild the picture, analysis the difference and report)

matlab例题 初学者试用 没有价值的东西(no value Example matlab beginners try something)

This MATLAB code generates a square circulant matrix using the vector V as the first row of the result if V is a row vector or as the first column of the result if V is a column vector. V may be any numeric data type or a character string.

将小波相邻系数相关性的降噪思想引入到冗余第2代小波中，提出了基于邻域相关性的冗余第2代小波降噪方法，该方法克服了传统阈值降噪没有考虑小波系数之间相关性的不足。(Aiming at fault feature extraction in the background of strong noise, a wavelet denoising idea by incorporating neighboring coefficients is introduced into redundant second generation wavelet case. A denoising method of redundant second generation wavelet using neighbor dependency is presented. It overcomes the deficiency of traditional thresholding approaches. In this method, an original signal is decomposed by redundant second generation wavelet, and the detail and approximation signals have the same length as the original signal. The detail signals at each scale are then processed by neighbor dependency. Finally, the approximation signal and processed detail signals are reconstructed by inverse transform of redundant second generation wavelet to realize the signal denoising. )

使用matlab画矢量箭头，可以算旋度散度等~(Draw vector arrows using matlab, you can curl divergence operator, etc. ~)

很不错的粒子滤波器入门程序，在一个外国网站下载的(Very good particle filter entry procedures, in a foreign Web site download)

factor of 32, with acceptable quality.What are the principles behind compression?A common characteristic of most images is that the neighboring pixels are correlated and therefore contain redundant information. The foremost task then is to find less correlated representation of the image. Two fundamental components of compression are redundancy and irrelevancy reduction. Redundancy
