Reading: C3 — Concentrated-Comprehensive Convolution (Semantic Segmentation)

Compared to ESPNet, ERFNet, DRN & ENet, Similar or Improved mIOU Achieved While Obtaining Smaller model sizes and fewer number of FLOPs


1. Concentrated-Comprehensive Convolution (C3)

Upper: Conventional, Bottom: Concentrated-Comprehensive Convolution (C3)

In summary, the C3 block combines both advantages of the depth-wise separable convolution and the dilated convolution.

2. C3 Module

Network structure of C3 and ESP module

3. Experimental Results

Ablation Study on Cityscape Test Set
SOTA Comparison on Cityscape
