change detection with IDL

Halcon视觉应用的三个小例子，又需要的朋友可以下载看看~~(Halcon visual application three small example, need friends can download and see ~ ~)

说明：  通过定义全局变量 实现simulink与gui的实时数据互通 用以电网仿真(By defining global variables Real time data communication between Simulink and GUI For power grid simulation)

可对灰度及彩色图像进行压缩及解压缩，通过变量名可以实现基于不同方式（多级树集合分裂spiht，ezw,stw,wdr等）的压缩，形如wcompress( c ,X,SAV_FILENAME,COMP_METHOD)(The wcompress command performs either compression or uncompression of grayscale or truecolor images.)

遥感图像除云软件，原理是图像同时期替换掉有云区域，使用IDL语言编写(remove cloud from remote sensing image)

采用拉普拉斯金字塔的图像融合程序，完成图像融合功能，需采用高于matlab2009的matlab(the image fusion source code using lap pyramid, you have to use the matlab version later than 2009.)

利用非线性结构张量处理一些图形问题，能够有效的解决和优化现成的处理方法(In this article, we introduce nonlinear versions of the popular structure tensor, also known as second moment matrix. These nonlinear structure tensors replace the Gaussian smoothing of the classical structure tensor by discontinuity-preserving nonlinear diffusions)

此程序为指纹识别中重要一步指纹分类的MATLAB源码(This program is an important step in fingerprint identification fingerprint classification MATLAB source code)

计算原始图像和过滤噪声后的图像的峰值信噪比(peak signal to noise ratio of image)

some fast feature extraction algorithms are addressed for joint retrieval of images compressed in JPEG and JPEG2000 formats. In order to avoid full decoding, three fast algorithms that convert block-based discrete cosine transform (BDCT) into wavelet transform are developed, so that wavelet-based features can be extracted from JPEG images as in JPEG2000 images.

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)
