基于sift的图像特征点提取和图像拼接，有可直接运行的代码和图片(Sift the image feature point extraction and image stitching, can be directly run the code and pictures)

说明：  包括canny，sobel，log等边缘检测的改进算法，使用效果良好(Including improved edge detection algorithms such as canny, sobel, log and so on, the application effect is good.)

FISM——结构相似度，它的功能为评价图像去噪效果，值越接近1，去噪结果越好。(FISM-- structural similarity, it functions is for the evaluation of image denoising effect, closer the value is to 1, better is the denoising results.)

说明：  迭代收缩阈值算法和快速收缩阈值迭代算法求解Lasso问题(Iterative Shrinkage Thresholding Algorithm (ISTA) for LASSO problem)

基于有限高斯混合模型的EM算法的源程序代码，里面有实验报告和运行结果。 (based on finite Gaussian mixture model of the EM algorithm source code, which has run reports and experimental results.)

读入图像，对图像进行预处理，随后检测边缘，对得到的图像进行二值化，然后进行hough变换，获得圆边界，将此图与原图叠加，增强边缘(Read in the image, the image pre-processing, followed by edge detection, binarization on the image to get, and then the hough transform to obtain the circular boundary, this map and the original image overlay to enhance the edge)

局部熵差图象匹配并行算法的分析和 功能以及和其他算法的比较(err)

说明：  采用霍夫曼技术实现压缩图像的重建，代码很详细，很不错。(Using Hoffman technology to achieve compressed image reconstruction, the code is very detailed, very good.)

Adult amblyopes can improve positional acuity through practice however, the neural mechanisms underlying this improvement are still not clear. In this study, seven adult amblyopes repeatedly practiced a position discrimination task in the presence of positional noise.

一般自然图像的梯度分布符合重尾分布，重尾分布也就是超拉普拉斯分布，根据这个特点进行图像复原。(The gradient of a natural image in line with heavy-tailed distribution, which is ultra-heavy-tailed distribution Laplace distribution, image restoration based on this feature.)
