说明：  利用遗传算法求多项式的最值,jiandande xy uexiGA(GA optimization)

基于最小相位雷克子波反褶积的matlab程序，有脉冲反褶积，最小平方反褶积和预测反褶积(Matlab program based on the the Leike Zi wave pulse deconvolution)

实现LLE算法，本算法是改进的LLE算法，主要是针对人脸图像的。()

今年刚更新的最新的工具箱SaliencyToolbox2.3.zip，做图像处理视觉注意力机制相关研究必备的工具。(This year has just updated the latest toolbox SaliencyToolbox2.3.zip, do image processing of visual attention mechanisms related research is an essential tool.)

说明：  PWLS算法主要用于CT重建前的投影数据处理，能够很好的用于CT迭代算法中，对图像进行去噪(PWLS algorithm is mainly used for projection data processing before CT reconstruction. It can be well used in CT iterative algorithm to denoise images.)

目的是改善影像质量，包括去除高频噪声与干扰，及影像边缘增强、线性增强以及去模糊等。分为低通滤波（平滑化）、高通滤波（锐化）和带通滤波。(The purpose is to improve the image quality, including the removal of high frequency noise and interference, and image edge enhancement, linear enhancement and deblurring. Into a low-pass filter (smoothing), high-pass filtering (sharpening) and bandpass filtering.)

图像轮廓提取，Snakes方法来提取CT图像的外轮廓(Snakes method)

基于svd的数字水印，信噪比比较高(Svd based digital watermarking, can also signal to noise ratio is relatively high)

利用梯度插值算法实现图像的去马赛克，图像质量大大提高(Using gradient interpolation algorithm to achieve image mosaic, image quality is greatly improved)

尺度空间sift算法的matlab实现，对理解算法步骤很有帮助(Scale space sift algorithm matlab to achieve an understanding of the steps of the algorithm helpful)
