Abstract

This paper discusses the results of the fourth edition of the Monocular Depth Estimation Challenge (MDEC), a challenge focusing on zero-shot generalization to the SYNS-Patches benchmark, a dataset featuring challenging environments in both natural and indoor settings. In this edition, we switched the evaluation protocol to perform least-squares rather than median alignment. The challenge received a total of 24 submissions outperforming the baselines on the test set: 10 among them submitted a report describing their approach, with a diffuse use of Depth Anything v2 at the core of most methods. The challenge winners improved 3D F-Score performance over the previous edition winners from 22.58% to 23.05%.
