图像的灰度处理

一个不错的图像缩放程序，可以对位图实现1：2的缩放。-a good image scaling procedures, the bitmap can achieve 1:2 zoom.

基于MAX7456的COSD的实用样例程序，完整实现了视频的迭加，效果不错。-MAX7456-based sample of COSD practical procedures, a full implementation of the superposition of the video were getting good results.

This code implements the well-known Chan-Vese segmentation algorithm from the paper "Active Contours Without Edges." This technique deforms an initial curve so that it separates foreground from background based on the means of the two regions. The technique is very robust to initialization and gives very nice results when there is a difference between the foreground and background means. This code uses active contours and level sets in the implementation. It could also serve as a good framework for implementing all kinds of region-based active contour energies. 1.) Download 2.)

指纹识别代码 demo目录： fvs_enhancer：指纹增强程序，描述了如何使用该库增强指纹图像。原图像和目标图 像都是位图。 fvs_direction：描述了如何提取方向图。输入图像必须是归一化的图像，这样才能 有较好的效果。输出图像覆盖于输入图像之上。 fvs_createtestimages：该程序用来产生调试过程中可能会用到的一些位图图像，这 些图像是不同角度和不同间隔的条纹。产生图像的文件名命名方式如下： testimgSSSDDD.bmp 其中，SSS代表条纹间隔（像素个数），DDD代表方向的角度。 fvs_thinner：描述了怎样细化一个指纹图像。细化后的图像尽可能的代表了指纹的 脊线。 fvs_minutia：显示了如何从细化后的指纹图像中获得细节点集合。这一部分目前做 的效果不好，提取出的伪细节点太多。 fvs_mask：计算有效的指纹区域（剔除非指纹区域以及模糊指纹区域）。 include目录： 包含了头文件。 src目录： 包含了指纹识别中各种算法的实现代码。这些代码的使用方法可以参见demo目录中的 例程。 -fingerprint identification code demo directory : fvs_enhancer : fingerprint enhancement procedures describes how to enhance the use of the fingerprint image. The original image and objectives are bitmap images. Fvs_direction : describes how to extract the direction of the map. Input image must be a normalized image, in order to have better results. Image output coverage in the input image above. Fvs_createtestimages : The procedure used to produce debugging process
