Abstract
An image encoding method includes determining N P-frames from a sequence of images, determining a source refreshing region in each one of the P-frames, obtaining reconstructed images corresponding to the source refreshing regions by performing a first encoding on the source refreshing regions, obtaining updated P-frames by updating the source refreshing regions with the reconstructed images, and performing a second encoding on the updated P-frames.
