Why CNN for Image?

CNN 经常作用于图像识别。

Some patterns are much smaller than the whole image

The same patterns appear in different regions

同样的pattern，在image里面，他可能会出现在image不同的部分，但是它们代表的是同样的含义，同样的形状，也有同样的neural，同样的参数，detector就可以侦测出来。

Subsampling the pixels will not change the object

做Subsampling使图片变小对影响辨识没什么影响
