RESUMO

This work aims to evaluate the performance presented by lapped transforms, wavelets and DCT in standards JPEG2000 and H.264/AVC coders. Even though there is much of information about the comparison of those transforms in many coders, there is little information available in literature relative to the performs of the performs of these transforms in the coders used. It is also compared to other forms of overlaping as intra frame prediction, used in H.264/AVC coder.
