Abstract
Systems, devices and methods are provided for video encoding and decoding. An example method includes: analyzing one or more input images; obtaining a background image from the one or more input images; encoding the background image to obtain a background frame; decoding the background frame to obtain a reconstructed image of the background frame; obtaining a first image from the one or more input images; encoding at least partially the first image to obtain a refreshment frame based at least in part on a difference between the first image and the reconstructed image of the background frame; obtaining a second image from the one or more input images; encoding at least partially the second image to obtain a common frame; and generating a video bit stream based at least in part on the background frame, the refreshment frame and the common frame.
