转换JPEG格式的图片，有多种选择模式。 多种选择模式

实现图像的几何变换，包括缩放，镜像，旋转等。

image processing and image registration

这段代码是关于边界链码提取的,采用MATLAB编写,但是还有一些欠缺-This code is on the boundary chain code extraction, using MATLAB to prepare, but there are still some lack of

walsh变换的算法实现，函数结构，很方便移植！-walsh transform algorithm, function structure, transplants easily!

用小波变换对图象进行灰度处理Wavelet-Using Wavelet Transform of image gray-scale deal with Wavelet

纹理寻址 -Addressable addressable texture texture

关于对图片加噪声的操作（椒盐噪声），分别加椒噪声、盐噪声和椒盐噪声-With regard to the operation of the picture plus noise (salt & pepper noise), respectively, plus pepper noise, noise and salt, Salt & Pepper Noise

含有pca和kpca算法，具有很好的在图像处理方面的应用-contain pca and kpca algorithm, is very good in image processing the application

图像的几种改善处理。包括平滑锐化，这两可函数需配合我上传的opentrim使用，还有灰度拉伸，灰度均衡。这两个函数可以在任何能得到只想图像像素区指针的情况下使用。-Improve the handling of several images. Including smooth sharpening, these two functions need to be uploaded with opentrim I use, as well as tensile gray, gray balance. These two functions can be in any image pixel area just want to use pointer.

算法用来求出道路的主方向，便于后续道路提取；
