JPEG压缩和解压缩源代码, 其中包含了把一副图像按照JPEG格式存储。-JPEG image compress and de-compress source code. it main contain the JPEG image processing.

MyDIP C++图像处理程序源代码，实现图片灰度处理、图像缩放、图像变换、图像边缘与轮廓的相关处理等。关于源码内的Template()函数：作用是用指定的模板（任意大小）来对图像进行操作，参数iTempH指定模板 　　 * 的高度，参数iTempW指定模板的宽度，参数iTempMX和iTempMY指定模板的中心 　　 * 元素坐标，参数fpArray指定模板元素，fCoef指定系数。 　　关于PrewittDIB()函数：作用是用Prewitt边缘检测算子对图像进行边缘检测运

it is basic step to compress image which is lossless.. what lossless mean ? image which can be reproduce completely after compression.. check it out the code and the data set
