preprocessing

改进的分水岭算法，能够较好地提取对象轮廓、准确得到物体边界的优点。在MATLAB6.5下顺利编译通过(improve the watershed algorithm can be used to extract object contours, to be precise object boundary advantages. In MATLAB6.5 smoothly through the compiler)

C#调用DLL实现图像文字识别(OCR)(C # call DLL realize image character recognition (OCR))

说明：  1.学习使用fft2,ifft2,fftshift,ifftshift函数。用fft2函数对”lena.bmp”做二维傅立叶变换，并显示其频谱，用fftshift函数将频谱坐标原点移动到图像中心。用ifft2函数做傅立叶反变换。（提示：显示频谱时，可以先对频谱取对数，这样可以压缩动态范围很大的频谱，获得更好的显示效果）(1. Learn to use fft2, ifft2, fftshift, ifftshift functions. With the FFT 2 function, the lena.bmp'The two-dimensional Fourier transform is performed and the spectrum is displayed. The origin of the spectrum coordinate is moved to the center of the image by using the FFT shift function. The inverse Fourier transform is done with ifft2 function. (Note: when displaying the spectrum, the logarithm of the spectrum can be taken first, so that the spectrum with a large dynamic range can be compressed to obtain better display effect.))

Unix系统下，小波包变换的实现源码实例，，当然，稍作改动也可用于windows系统下。 (Unix systems, the instance of the wavelet packet transform source, of course, some minor changes can also be used in the windows system.)

说明：  matlab地图工具包m_map的中文说明书，内含各种应用个例(Matlab map toolkit M_ The Chinese Manual of map contains various application examples)

基于MATLAB图像处理的车辆检测与识别（可以看看）基于MATLAB图像处理的车辆检测与识别（可以看看(MATLAB image processing based vehicle detection and recognition (can see) MATLAB image processing based vehicle detection and recognition (can see)

包涵了计算影像的几种质量指标，这些指标都是全局指标，对影像质量评价有一定作用(Image Quality Index ：IFC、Q4、QNR、VIF)

说明：  这个源程序的主要功能是实现图像基于拉普拉斯金字塔的图像融合(The primary function of the source image is Laplacian pyramid-based image fusion)
