This is the implementation of the work: Depth-aware Volume Attention for Texture-less Stereo Matching.

Introduction

Stereo matching in large texture-less scenarios with perspective effect is challenging. In this paper, taking road surface as a typical scenario, we reveal the performance decrease due to the texture deterioration in natural images. We introduce the depth-aware texture hierarchy attention and target-aware disparity attention modules to focus on the texture hierarchy. We propose a noval metric named Weighted Relative Depth Error (WRDE), which provides comprehensive assessment of depth-wise performance.
