Multiple-description video coding through adaptive segmentation
2004
Applications of Digital Image Processing XXVII
Each approach to multiple description coding consists of a tradeoff between compression efficiency and robustness. ...
Previous approaches to multiple description coding have made the assumption that a single segmentation method would be used for an entire sequence. ...
In some cases it is the opposite, and robustness may be sacrificed for coding efficiency. The system does not need to be balanced either; could be weighted more heavily than , and so on. ...
