Apple Dense Material Segmentation (DMS) – Stratified 80/10/10 Split
A pixel-level material segmentation dataset containing ~41K images with dense annotations across 57 material categories. Originally released by Apple as part of the Dense Material Segmentation (DMS) research project.
This version uses a custom stratified 80/10/10 split (vs Apple's original 54/23/23) to maximise training data while maintaining representative validation and test sets.
Why a Custom Split?… See the full description on the dataset page: https://huggingface.co/datasets/AllanK24/apple-dms-materials-v2.
