Common-Residual Motion
A motion decomposition mechanism that separates scene motion into a common component and a residual component, used to resolve the ambiguity between camera motion and soft-tissue deformation in endoscopic scenes, thereby improving geometric estimation and 3D tracking accuracy.
Timeline (last 90 days)
SCOPE-4D introduces a Common-Residual Motion (CRM) mechanism that decomposes motion into a common motion component and a residual motion component to alleviate the difficulty of distinguishing camera motion from tissue motion.
Experiments show that combining CRM with trajectory supervision further improves camera and depth estimation on top of geometric fine-tuning, and endows the model with dense 3D tissue tracking capability.
