摘要：

In this paper, we propose a new error protection technique for JPEG2000 encoded images that exploits the codestream layer structure. Prior to transmission, data in the top layer is duplicated and protected by an FEC code. This data is then embedded into the bottom layer. In the receiver, a post-transmission process is applied to the codestream that extracts the embedded data for error recovery purposes. Our proposal offers several advantages: preserves the same codestream structure as the one in the JPEG2000 part I standard, provides multilevel error protection for the top layer, and can be merged with the existing error resilience technique. Hence, the method accommodates the new requirements for wireless JPEG2000 (JPWL/JPEG2000 part 11). Simulations in an OFDM transmission environment showed the effectiveness of the proposed method.
