【实例简介】本数据集数据取自 https://lttm.dei.unipd.it//downloads/gesture/ 原数据集包含了14个人采集的共1400张样本，共10种手势。包括RGB图像、深度信息等，原图大小1280*960。 本数据集只选用了RGB图像，并将图像缩小为400*300。同时对所有的手势进行了样本标记，以PascalVOC格式记录。 所有标记坐标均以（0,0）为图像左上角点。

本ZIP文件包含了经典的手写数字的bmp数据，共{0,1,2，……，9}10个类，每个类包含500个数据；然后对图片进行二值化处理，采用patch来对每张image提出特征，最后设计神经网络对特征进行训练，并用得到的net来测试TestingSet，经过调解参数，测试精度可以达到95%左右。整个实现过程是基于matlab语言的，code清晰，明了，简单易懂，绝对值得算法爱好者探究。
