1. caffe matlab 接口提供了提取ｆｅａｔｕｒｅ的脚本，但是由于中间要对这些图像进行ＲＧＢ ---> BGR 的变换，卧槽，灰度图没有三通道啊？怎么破？从上午就在纠结怎么会跑着跑着程序就报错了，尼玛，坑啊。。。
如何解决这个问题 ？？
-----------------------------------------------------------
我把灰度图给扔了，谢谢！
2. If I use the color images mixed with gray images together for CNN training, what will happened ???
well, it is really a stupid question, and I do a test about this problem due to the existance of gray images in caltech-256 dataset. The accuracy becoming 0 gradiually...
That's what happened. It is really sad ... Just throw the gray image immediately ...
