Semantic Segmentation Modules

Deeper Atrous Spatial Pyramid Pooling

Introduced by Emara et al. in LiteSeg: A Novel Lightweight ConvNet for Semantic Segmentation

DASPP is a deeper version of the ASPP module (the latter from DeepLabv3) that adds standard 3 × 3 convolution after 3 × 3 dilated convolutions to refine the features and also fusing the input and the output of the DASPP module via short residual connection. Also, the number of convolution filters of ASPP is reduced from 255 to 96 to gain computational performance.
