<title>Multiresolutional encoding and decoding in embedded image and video coders</title>

Abstract: We address multiresolutional encoding and decoding within the embedded zerotree wavelet (EZW) framework for both images and video. By varying a resolution parameter, one can obtain decoded images at different resolutions from one single encoded bitstream, which is already rate scalable for EZW coders. Similarly one can decode video sequences at different rates and different spatial and temporal resolutions from one bitstream. Furthermore, a layered bitstream can be generated with multiresolutional encoding, fr… Show more

“…Figures 3 (a) and (b) show the layered bit streams generated by the previous multiresolutional encoding [2] and the proposed multiresolutional encoding at 1 bpp and 0.1 bpp, respectively. In the figures, we can see that the first layer of the bit stream generated by the previous multiresolutional encoding method is much longer than the first layer of our algorithm.…”

“…In the previous work [2], they decoded the whole bit stream and selected the necessary coefficients to reconstruct an image they wanted. It is difficult to use this function in the narrow bandwidth environment because the whole bit stream should be transmitted to reconstruct even a small image.…”

“…By reordering the transmitted bit stream, the SPIHT algorithm can be made spatially scalable [18], [29]. Compared against SPIHT without arithmetic coding, the spatially scalable SPIHT has no loss in performance (PSNR versus bit rate at the final full size) and retains some progressivity.…”

“…In [30], the resolution and frame rate scalability is obtained by partitioning and/or reordering the bit stream from the 3-D SPIHT. A comprehensive version of the 3-D SPIHT is presented in [14].…”
