A method is proposed to encode multiple regions of interest in the JPEG2000 image-coding framework. The algorithm is based on the rearrangement of packets in the code-stream to place the regions of interest before the background coefficients. In order to improve the quality of the reconstructed image, partial background information is included with the(More)
An adaptive unequal channel protection technique is proposed for JPEG2000 images by exploiting the hierarchical structure of the bit-stream. The proposed technique takes into account the effect of channel errors in different packets of the bit-stream in order to optimally protect the coded data. For a given transmission bandwidth and multi-layered JPEG2000(More)
