Abstract
It is proposed a Method and System for Global Motion Estimation and Compensation. The system operates on two depth maps which contain a reference depth map and a current depth map as well as their associated texture images if available. The system executes four major steps which are feature detection (step 1), global motion compensation (GMC) (step 2), major moving objects (MMO) detection and the estimation of their motion parameters denoted as major motion parameters (MMPs) (step 3), and local motion compensation (LMC) of macroblocks or other coding/prediction units (step 4). The output of the system is the global motion parameters (GMPs), major moving objects (MMOs) and MMPs, the local motion vectors (LMVs), and the coding modes.
