| "description": "SynGlass is a large-scale synthetic dataset for fine-grained eyeglasses segmentation, introduced at BMVC 2026. It contains 332,928 renders (1024x1024 PNG) of 128 photorealistic RenderPeople avatars wearing 867 distinct 3D-scanned eyeglass models, each combination rendered in Unreal Engine 5 under 3 random near-frontal head poses in an indoor living-room scene. Every render comes with pixel-accurate lens and frame segmentation masks generated directly from the 3D geometry (the masks additionally encode normalized camera-view depth in their RGBA channels) and a per-render JSON file with head pose, head/eye positions and camera parameters. Each eyeglass model is labelled with frame family (full-rim / semi-rimless / rimless), material (plastic / metal), lens shape (rectangle, square, round, oval, aviator, cat-eye, other) and lens type (clear / sunglasses); each avatar with gender, age group and ethnicity. The split is by eyeglass model: 776 models (297,984 renders) for training and 91 held-out models whose 22,304 pose-matched renders form the test set; the remaining 12,640 renders of the test models are kept in a separate test_pool split and must not be used for training. Subject and eyeglass identifiers are anonymized (subject_NNN, glasses_NNN). Each row of manifest/sessions.csv is one render; resource paths are relative to the dataset root and start with the subject folder.", |
