Abstract

In this paper, iterative projection algorithms are presented to reconstruct visually pleasing images from Block Discrete Cosine Transform (BDCT) compressed image data. Two algorithms are proposed. The first is based on the theory of Projections Onto Convex Sets (POCS). The second is motivated by the theory of POCS. Experimental results are presented which demonstrate that the proposed algorithms yield superior images to those obtained by direct reconstruction from the compressed data only.
