基于多特征描述和DPF区域匹配的图像检索-Based on multi-feature description and matching DPF Regional Image Retrieval

2D图象处理程序，类似FRACTAL STUDIO功能不用说了非常强大，这是源代码-2D image processing procedures, similar FRACTAL STUDIO features a very powerful Needless to say, this is the source code

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.

SAR图像中有很多质量问题，增益是其中之一，这里提供了SAR图像中增益检测的算法-SAR image quality of a lot of issues, one of which is Gain, here to provide a SAR image detection algorithm Gain

图象的几何变换 打开一幅位图，实现几何变换 命令行编译过程如下 vcvars32 rc bmp.rc cl geotrans.c bmp.res user32.lib gdi32.lib-Images of geometric transformations to open a bitmap, geometric transformations realize the process of command-line compiler is as follows vcvars32rc bmp.rccl geotrans.c bmp.res user32.lib gdi32.lib

这是一个非常好的图像二值化电路的源代码，希望能帮助大家-This is a very good image binarization circuit

图像处理方面，主要完成将二值数字水印嵌入到原图像中完成隐藏，同时完成了提取过程的编码-Image processing, the main value of the completion of the second digital watermark is embedded in the completion of the original image to hide, at the same time to complete the extraction process of encoding

Visual C++MATLAB图像处理与识别实用案例精选之离形余弦变换的程序例子-Visual C MATLAB image processing and recognition of practical cases selected from the form"s Cosine Transform procedures examples

数字图像处理大作业。用vc.net写的各向异性扩散滤波程序，算法是PERONA―MALIK提出的离散方法，提供各项同性扩散处理结果做对比。-Digital image processing large operation. Vc.net written using anisotropic diffusion filtering procedure, the algorithm is proposed PERONA-MALIK discrete way to deal with the results of the proliferation of the same sex to do comparison.
