1. ExImage是在DIB类的基础上，扩展了一些基本图像处理功能，除图像格式库外，所有图像处理算法均为自主开发，各处理算法可单独使用。 2. ExImage主要功能包括：颜色增强、校正、配准、拼接、复原、融合、分析、压缩编码等。 关键词：彩色图像处理、自适应中值滤波、图像增强、几何校正、图像配准、图像拼接、图像融合、图像压缩。 (ExImage Image processing toolkit)

说明：  对有噪声的图像进行图像复原，通过迭代算法实现此功能(Image restoration for noisy images, this function is implemented by an iterative algorithm)

说明：  usps数据库为标准手写数据库，此为mat数据文件，含训练集和测试(USPS database is a standard handwritten database, which is a mat data file, including training set and test)

很好用的svm工具箱，dagsvm对于图像分类效果非常好，分类精度很高，代码清洗简单。(Good use of SVM Toolbox, dagsvm for image classification effect is very good, very high classification accuracy, code cleaning easy.)

基于lloyd-max最佳量化器的量化程序，如有需要可随时下载。(Based on the best lloyd-max quantizer quantization procedure, if necessary, at any time to download.)

基于巴谷星表星挑选出等小于2的恒星，利用matlab实现可生成任意方向的导航星星图以作为天文导航识别定位定姿依据的程序。(Pick out the star catalog prakob etc. less than 2 stars for navigation based on star map can be generated in any direction as celestial navigation positioning and orientation according to the recognition procedure using matlab.)

车牌矫正,对于一写不够标准的车牌进行矫正，让车牌更容易被分割(Plate correction, not enough for a standard license plate write to correct, so more likely to be split plate)

维纳滤波对图像去噪与最小二乘方滤波对图像去噪的比较(Wiener filter for image denoising with the least squares filter for image denoising comparison)

说明：  三种emd去噪方法：1、直接使用小波阈值，进行硬阈值去噪；2、使用具有emd分解特性的阈值去噪；3、emd分解后的平移不变去噪。(Three kinds of EMD denoising methods: 1. Direct use of wavelet threshold for hard threshold denoising; 2. Use of threshold denoising with EMD decomposition characteristics; 3. Translation invariant denoising after EMD decomposition.)

Pcnn与otsu结合，自适应找出Pcnn点火次数！(It is pcnn base on OTSU,can stop the program adaptive.)
