MAS3K (MAS3K: An Open Dataset for Marine Animal Segmentation)
MAS3K contains a total of 3,103 images, where 1,588 are for camouflaged cases, 1,322 are for common cases, and 193 are underwater images in absence of marine animals. The marine animal categories in MAS3K cover both vertebrate and invertebrate, including seven super-classes, e.g., mammals, reptile, arthropod, and marine fish, etc. Under the super-classes, MAS3K dataset has 37 sub-classes, e.g., crab, starfish, shark, and turtle, etc.

Papers archive 2025-07-28
4 shown of 4 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 4. The Syntology column is from Syntology's graph (read 2026-09-24), stated per sample; it is not part of any archive number.
