Edge sensitive subband coding of images

Institut für Signalverarbeitung

Abstract

In this paper, we introduce a family of novel edge preserving image coding techniques based on the discrete wavelet transform (DWT). These techniques utilize the edge map (which not necessarily contains closed curves) of the processed image or its subbands in the way that no filtering over edges is performed. This results in a reduction of power in the higher frequency bands. The achievable savings are higher than the additional bit rate needed for transmission of the edge map.
