Parallax-Attention Mechanism (PAM)

Reposity for "Parallax Attention for Unsupervised Stereo Correspondence Learning", IEEE TPAMI 2020

[arXiv]

Overview

1. Network Architecture

2. Left-Right Consistency & Cycle Consistency

3. Valid Mask

Applications

1. PAM for Unsupervised Stereo Matching (PASMnet) [code]

1.1 Overview

1.2 Results

2. PAM for Stereo Image Super-Resolution (PASSRnet) [code]

2.1 Overview

2.2 Results

3. PAM for Other Applications

Our PAM provides a compact and flexible module to perform feature fusion or information interaction for stereo images without explicit disparity estimation, which can be extended to stereo 3D object detection, stereo image restoration (e.g., super-resolution [1,2,3,4], denoising, deblurring, deraining and dehazing [5]), stereo image style transfer, multi-view stereo, and many other tasks [6,7].
