AIM-500 (Automatic Image Matting-500)
AIM-500 is the first natural image matting test set, contains 500 high-resolution real-world natural images from three types of images (salient opaque foregrounds, salient transparent/meticulous foregrounds, non-salient foregrounds), and multiple categories. The amount of each category is shown in the following table.
| Portrait | Animal | Transparent | Plant | Furniture | Toy | Fruit |
|---|---|---|---|---|---|---|
| 100 | 200 | 34 | 75 | 45 | 36 | 10 |

Papers archive 2025-07-28
6 shown of 6 papers with a leaderboard row on this dataset's benchmarks, newest first. The archive's own "papers using this dataset" list was never published, so this is the benchmark-backed subset; the archive's count for this dataset is 23. The Syntology column is from Syntology's graph (read 2026-09-24), stated per sample; it is not part of any archive number.
