图像经过卷积后的尺寸计算公式

Image size after convolusion:

　　　　$\frac{n-k+2p}{s}+1$

where n is the width (or height) of the image,

　　    k is the kernel size,

　　    p is the padding,

　　    s is the stride.

上面公式简写为：

 

Image size after pooling:

　　　　$\frac{n-f}{s}+1$

where n is the width (or height) of the image,

　　   f is the pooling size,

　　   s is the stride.
