基于VC++6.0的JPEG压缩编码 有自己编写的Huffman查表 写jpeg文件等函数.可以完成标准256*256图的bmp到jpg的压缩,其生成的jpg图片可以用画图软件打开.暂时未完成像素没有16对齐的图片压缩.-VC++6.0 based on the JPEG compression Huffman coding which has its own look-up table prepared to write jpeg files, and so function Can complete the standard 256* 256 map bmp to jpg compression, the resulting jpg images can be opened with Paint software. Not yet completed pixel of the image is not compressed 16-aligned.

实现图像的增强，由均值与事先设定的阈值比较，得到不同的参数，再通过这些参数进行图像的增强。-Realize enhanced image by the mean and the pre-set threshold compared with different parameters, these parameters through image enhancement.

给出一个矩型框，画圆的算法-is a rectangular frame, the algorithm Circle

本目录主要包括：文档和两个源代码。 其中一个源代码是识别程序的，另一个是一个矩阵类库的，书里面也使用过，所以一并附上。 因为已经保存了训练好的网络权值，所以第一次使用识别程序时，可以直接运行Release目录下的可执行文件，然后对图片目录中的测试图片进行读入、识别。 当然读者也可以自行用训练样本训练网络，不过要特别注意训练样本的选择，否则可能造成识别率很低。训练样本选择的原则是，尽可能的有代表性，在训练时间不至于太长的情况下，训练样本数目尽量多。-Catalog include: documentation and two source code. One of the source code is the identification procedures, and the other is a matrix class library, the book which is also used, so be accompanied. As it has saved the trained network weights, so the first time the use of identification procedures, he can run Release directory of the executable file, and then the picture directory to read the test pictures to identify. Of course, the reader can also be its own training network with training samples, but pay special attention to the training samples, otherwise it may result in the recognition rate is very low. Training sample selection principle is that as much as possible representative, in the long training time Buzhi Yu circumstan
