Fast-SCNN is a lightweight neural network designed for real-time semantic segmentation on high-resolution images. It reduces computation by making the early layers a learning to downsample module shared by both branches, and uses a two-branch structure that merges a global feature extraction branch with a shallow spatial branch. It targets environments with tight memory and speed constraints, such as embedded devices, and implementations are included in libraries such as mmsegmentation.
