[DL] 13. Convolution and Pooling Variants (Dilated Convolution, SPP, ASPP)

1. Dilated Convolution

Equation 1. Dilated Convolution with dilation rate r
Standard convolution, when r = 1
Dilated Convolution, when r = 2
Figure 1. Illustration of 3x3 Dilated convolution. Left panel: dilation rate r = 1, equivalent to the normal convolution, center panel: dilation rate r=2, right panel: r=3, from link

2. Spatial Pyramid Pooling (SPP)
