An Efficient MDC based Set Partitioned Embedded Block Image Coding

Abstract

In this paper, fast, efficient, simple and widely used Set Partitioned Embedded bloCK based coding is done onMultiple Descriptions of transformed image. The maximum potential of this type of coding can be exploited with discretewavelet transform (DWT) of images. Two correlated descriptions are generated from a wavelet transformed imageto ensure meaningful transmission of the image over noise prone wireless channels. These correlated descriptions areencoded by set partitioning technique through SPECK coders and transmitted over wireless channels. Quality ofreconstructed image at the decoder side depends upon the number of descriptions received. More the number ofdescriptions received at output side, more enhance the quality of reconstructed image. However, if any of the multipledescription is lost, the receive can estimate it exploiting the correlation between the descriptions. The simulationsperformed on an image on MATLAB gives decent performance and results even after half of the descriptions islost in transmissio
