C# 鼠标拖拽图像 实例源码

彩色图像直方图均衡化：把一副彩色图像分成红绿蓝三个通道，对每一个通道先进行均衡化，然后再合并三个通道，得到整幅图像的直方图均衡化。(Color image histogram equalization: put a pair of color image into red, green, blue three channels, to each channel to equalization, then merge three channels, get the whole image histogram equalization.)

粒子滤波去噪 含噪情况下应用粒子滤波技术可以去除噪声(Particle filtering noise with noise case using particle filtering techniques can remove noise)

量化离散余弦变换系数的程序实现及其效果的检测。过程中使用了8x8的分块方法。首先计算每块的离散余弦变换（DCT)；然后量化了DCT的系数； 最后进行了反离散余弦变换(iDCT). 程序中还可以设定缩放系数。(Quantify the discrete cosine transform coefficients procedure and its effect detection. The process used in the 8x8 sub-block method. First calculate the block discrete cosine transform (DCT), quantization of the DCT coefficient Finally, the inverse discrete cosine transform (iDCT) program can also set the scaling factor.)

图像DFT，C语言编写的代码，附带几个另外的处理，(Image DFT, C language code, with some additional processing,)

根据指定字符分割字符串，VC++精选编程源码，很好的参考。(According to the specified character segmentation character string, VC++ select programming source code, a good reference.)

根据图像的边界进行轮廓跟踪来获取图像的外轮廓线(The image of the contour tracking to obtain an image of the outer boundary contour)

影像仿射变换特征提取，结合 sift 等局部特征可以处理较大视角变化下的图像匹配。(This is an implementation of Hessian-Affine detector. )

本文主要是用matlab提供的小波包对图像进行分解、压缩、重构(This article is mainly used to provide matlab wavelet packet decomposition of images, compression, Reconstruction)

说明：  这是一个用C++语言实现一个指纹识别程序，要求满足FVC国际竞赛标准，并在学校建立的指纹库上实测。程序里应用到的技术有：中值滤波、直方图均衡化、脊线方向提取、Gabor滤波、指纹细化、特征提取、特征点过滤、基于局部特征点的特征匹配(This is a C++ Language realization of a fingerprint identification procedure, the requirements FVC meet international competition standards, and established in the school library on the measured fingerprint. Program applied to the technology are as follows: median filter, histogram equalization, the direction of the ridge line extraction, Gabor filtering, fingerprint thinning, feature extraction, feature point filtering, based on local feature points of the feature matching)
