| Abstract: | This paper simply introduces the application of wavelet in image processing and the algorithm of EZW. According to the shortage of EZW, an improved method is proposed, namely encoding the low frequency subband independently, detecting the edge in high subband. Experimental results show that the improved algorithm is superior to EZW by contrasting PSNR/db, the time of coding and decoding. |
