Abstract:
Systems (490), methods (340), and machine-readable and executable instructions (428) are provided for depth mask assisted video stabilization. Depth mask assisted video stabilization can include creating a first depth mask from a first frame (101, 201) and a second depth mask from a second frame (102, 202) to obtain depth information (342) and defining a first list of feature points (111-1a, 111-2a, 111-3a, 111-4a, 113-1a, 113-2a, 113-3a, 113-4a, 113-5a) from the first frame (101, 201) and a second list of feature points (111-1b, 111-2b, 111-3b, 111-4b, 113-1b, 113-2b, 113-3b, 113-4b, 113-5b) from the second frame (102, 202) (344). Depth mask assisted video stabilization can also include comparing feature points from the first list of feature points (111-1a-111-4a, 113-1a-113-5a) with feature points from the second list of feature points (111-1b-111-4b, 113-1b-113-5b) to find a number of common feature point pairs (111-1a, 111-1b), (111-2a, 111-2b), (111-3a, 111-3b), (111-4a, 111-4b), (113-1a, 113-1b), (113-2a, 113-2b), (113-3a, 113-3b), (113-4a, 113-4b), (113-5a, 113-5b)) (345) and creating a number of motion matrices from the common feature point pairs ((111-1a, 111-1b), (111-2a, 111-2b), (111-3a, 111-3b), (111-4a, 111-4b), (113-1a, 113-1b), (113-2a, 113-2b), (113-3a, 113-3b), (113-4a, 113-4b), (113-5a, 113-5b)) (346). Depth mask assisted video stabilization can also include including the motion matrices in a correction matrix (348) and applying the inverse of the correction matrix to the second frame (102, 202) to perform video stabilization (350).
