HOT-POT method uses optimal transport for sparse stereo matching

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel approach called HOT-POT for sparse stereo matching, utilizing optimal transport (OT) to address challenges like occlusions and distortions in applications such as autonomous driving, robotics, and facial analysis. By formulating camera-projected points as lines and employing epipolar and 3D ray distances as cost functions for OT problems, the method leads to efficiently solvable assignment problems. The approach is further extended to unsupervised object matching through a hierarchical OT formulation, demonstrating effectiveness in feature and object matching, particularly in facial analysis tasks involving distinct landmarking conventions.
