Multi-resolution boundary encoding applied to region based still image and video encoding

摘要

A method and an associated apparatus applies multi-resolution boundary encoding to region based still image and video encoding, allowing better error correction for low frequency transmission. High frequency bands that are less protected may be discarded, leaving only lower frequency representation. By using JSCC techniques, a receiver with low resolution capability or low channel bandwidth may still render a close approximation of a boundary despite error in transmission.
