QDMouse4M: A Multi-View 3D Mouse Spontaneous Behavior Dataset with Quantum-Dot Markers

Quantitative analysis of animal behavior in neuroscience increasingly relies on accurate 3D pose, yet current large-scale mouse datasets with pose annotations are restricted to top-down views and suffer from occlusion and keypoint ambiguity. We introduce QDMouse4M, a six-view dataset of freely moving mice with physically grounded 2D and 3D keypoint annotations obtained from subdermal quantum-dot...
