The image quality and compression ratio trade-oos of ve diierent 176 144 pels quarter common intermediate format (QCIF) fractal image codecs are investigated by simulation. The average peak signal-to-noise ratio (PSNR) ranges from 29 dB to 37 dB, while the coding rate from 0.24 bit/pel (bpp) to 1.22 bit/pel, as seen in Table 1. Two of the candidate co-decs,(More)
