图像去噪

灰度变换元代码，用于matlab7.0以上版本(Picture Process)

实现图像配准:线性保角变换，投影变换及仿射变换。(Achieve image registration: linear conformal transformation, projection transformation and affine transformation.)

可以实现图像的重采样，通过设置参数来减小或增大图像尺寸(Resampling of the image can be achieved by setting parameters to decrease or increase the image size)

用来比较两张图片的相似程度的MATLAB程序(A MATLAB program used to compare the similarity between two pictures)

两个图像质量评价函数，psnr峰值信噪比，正则均方误差nmse，能可用于去噪图像和压缩图像的质量评价，很有用啊。(Two image quality evaluation of the function. Including psnr PSNR, it is mean-square error nmse other. Images can be used for de-noising and compression of image quality evaluation.)

说明：  一个立体系统相机标定，立体图像校正以及三维三角测量的多功能matlab工具箱。压缩包中包括一个PDF说明文档，和一个带有实验用图像的matlab程序压缩包。(A three-dimensional system, camera calibration, stereo image correction, as well as three-dimensional triangulation of multi-function matlab toolbox. Compressed package includes a PDF documentation, and one with an experimental image compression package matlab program.)

稀疏表示中字典学习算法KSVD的实现，可以得到冗余字典，代码内部有详细注释(The realization of the sparse representation of a dictionary learning algorithm KSVD, can get a redundant dictionary, internal has a detailed code comments)

基于粒子滤波与改进水平集的人手跟踪论文，论文中详细介绍了手势分割的实现算法(Based on particle filter and improve the level set of hand tracking paper, paper introduces the realization of gesture segmentation algorithm)

对图像进行修复，直方图均衡化处理，中值滤波和均值滤波(To repair the image, histogram equalization, median filtering and mean filtering)

Gabor滤波器的实现函数，与一般网上下载的不同，滤波效果更好，易于提取图像特征(Gabor filter implementation function, and general downloading different, better filtering, easy to extract image features)
