Title:
AN EFFICIENT HYBRID METHOD FOR EGO-MOTION FROM VIDEOS CAPTURED USING AN AERIAL CAMERA
Document Type and Number:
WIPO Patent Application WO/2017/209886
Kind Code:
A3
Abstract:
Described is a system for compensating for ego-motion during video processing. The system generates an initial estimate of camera ego-motion of a moving camera for consecutive image frame pairs of a video of a scene using a projected correlation method, the camera configured to capture the video from a moving platform. An optimal estimation of camera ego-motion is generated using the initial estimate as an input to a valley search method or an alternate line search method. All independent moving objects are detected in the scene using the described hybrid method at superior performance compared to existing methods while saving computational cost.
