Three Birds One Stone: A General Architecture for Salient Object Segmentation, Edge Detection and Skeleton Extraction

Understand

In this paper, we aim at solving pixel-wise binary problems, including salient object segmentation, skeleton extraction, and edge detection, by introducing a unified architecture.

• Previous works have proposed tailored methods for solving each of the three tasks independently.
• Here, we show that these tasks share some similarities that can be exploited for developing a unified framework.
• In particular, we introduce a horizontal cascade, each component of which is densely connected to the outputs of previous component.
