Abstract | This paper provides an in depth discussion and analysis into the wavelet transform as well as two important wavelet-based coding schemes, the Embedded Zerotree Wavelet (EZW) coding scheme and the Set Partitioning in Hierarchical Trees (SPIHT) coding scheme. The two algorithms are outlined and their performances are evaluated and compared with current compression standards like JPEG. Investigation into the resilience of these two wavelet coding schemes with regards to image transmission over error prone channels is also attained. An error coding scheme involving arithmetic coding with forbidden symbol and maximum a posteriori (MAP) decoding is proposed in order to improve the error resilience of the EZW and SPIHT schemes. |
