最近在看实例分割的相关算法，始终无法很好的理解反卷积的相关内容，在github上找到了大佬制作的卷积和反卷积动图，放在博客保存一波。

Convolution animations
N.B.: Blue maps are inputs, and cyan maps are outputs.

| No padding, strides | Padding, strides | Padding, strides (odd) |
Transposed convolution animations
N.B.: Blue maps are inputs, and cyan maps are outputs.

| No padding, strides, transposed | Padding, strides, transposed | Padding, strides, transposed (odd) |
Dilated convolution animations
N.B.: Blue maps are inputs, and cyan maps are outputs.
