Since the digital representation of raw video signals requires a high capacity, low complexity video coding algorithms must be defined to efficiently compress video sequences for storage and transmission purposes. The proper selection of a video coding algorithm in multimedia applications is an important factor that normally depends on the bandwidth availability and the minimum quality required. For instance, a surveillance application may only require limited quality, raising alarms on identification of a human body shape, and a user of a video telephone may be content with only sufficient video quality that enables him to recognise the facial features of...
