Monocular Depth Estimation Rankings
and 2D to 3D Video Conversion Rankings

Awesome Synthetic RGB-D Image Datasets for Training HD Video Depth Estimation Models

📝 Note: By way of exception, I include one and only one image dataset, due to its size: 700K scenes and the incredible improvement in depth estimation results of the fine-tuned Depth Anything V2 ViT-B model on MegaSynth and evaluated on Hypersim. See the results in Table 6.

📝 Note: 1) See Figure 4 2) The ranking order is determined in the first instance by a direct comparison of the scores of two models in the same paper. If there is no such direct comparison in any paper or there is a disagreement in different papers, the ranking order is determined by the best score of the compared two models in all papers that are shown in the columns as data sources. The DepthCrafter rank is based on the latest version 1.0.1.

NYU-Depth V2: AbsRel<=0.0424 (relative depth)

📝 Note: The ranking order is determined in the first instance by a direct comparison of the scores of two models in the same paper. If there is no such direct comparison in any paper or there is a disagreement in different papers, the ranking order is determined by the best score of the compared two models in all papers that are shown in the columns as data sources. The Metric3D v2 ViT-Large rank is not based on a score of 0.134, which is probably just an anomaly.
