Abstract :
Current video coding techniques provide very good performance both in terms of compression ratio as well as image quality. In practice, the required computational complexity tends to be significant. Environments that have significant power or computational performance restrictions would benefit from improved coding and decoding, especially if complexity is kept manageably low. In this paper the design of a symmetric codec with significantly low complexity is shown, particularly suited and optimized for mobile environments. Low-complexity algorithms and approaches are employed, and results obtained with a software model are provided both in terms of complexity as far as visual quality.
