TL;DRAbstract

Wireless imaging services suffer large impairments due to the hostile nature of the wireless channel. Given the limited and expensive channel bandwidth and the high data demanding nature of these services, it becomes a challenging task to provide high quality of service in such error prone channels. Clearly, suitable error protection is necessary in order to maintain sufficient quality of these services under various channel conditions. In this report, therefore, we have investigated different channel error protection schemes for a wide range of channel conditions and coding rates. Two unequal error protection (UEP) schemes have been examined for JPEG2000 images exploiting useful features of the JPEG2000 codestream and using the error protection tool set provided by wireless JPEG2000 (JPWL). Taking the importance of the initial codestream packets on the reconstruction of the image at the receiver into account, the first scheme uses all the additional bandwidth resources in protecting t
