Abstract
A system and method relate to calculating a first edge map associated with a reference video frame, generating a second edge map associated with an incoming video frame, generating an offset between the reference video frame and the video frame based on a first frequency domain representation of the first edge map and a second frequency domain representation of the second edge map, translating locations of a plurality of pixels of the incoming video frame according to the calculated offset to align the incoming video frame with respect to the reference video frame, and transmitting the aligned video frame to a downstream device.
