1. A method comprising:
receiving, by a receiving device, a set of parameters or coefficients associated with a current video frame of a video transmission from a transmitting device, the set of parameters or coefficients generated from locations of object landmark points characterizing object content in the current video frame, wherein the receiving device receives the set of parameters or coefficients without the current video frame; performing, by the receiving device, a search, using the set of parameters or coefficients, of a data structure storing previously received video frames of the video transmission; retrieving, by the receiving device, a previously stored video frame containing similar object content of the current video frame based on performing the search of the data structure; and displaying, by the receiving device, the retrieved video frame in place of the current video frame.
