In this paper we propose the use of intra-frame prediction with lapped transforms for image coding. Both lapped transforms and intra prediction exploit the redundancies of neighbo...

A lapped biorthogonal transform adapted for local directionality of an image is proposed. The proposed transform consists of overlapping basis functions and non-overlapping basis ...

Integer lapped orthogonal transforms (LOTs) are vital technologies for the unification of lossless and lossy image coding, called losslessto-lossy image coding. In this paper, we...
