Abstract
Two coding methods for arbitrarily shaped objects in still images using the lapped orthogonal transform (LOT) are proposed. The LOT is applied to the projection onto convex sets (POCS) based algorithm and the shape adaptive-d iscrete cosine transform (SA-DCT) with the even number of basis vectors, Si mulation results show improved reconstruction quality compared with the con ventional methods.
