Abstract
JPEG 2000 stands out among the image compression standards as its facilities to provide tools for error-resilience and compression efficiency and image quality. However, these tools cannot correct transmission errors, they can only detect the error, conceal it, and resynchronize the decoder. Therefore, they are not efficient in wireless scenarios. Recently, JPEG 2000 has been extended to support efficient transmissions of JPEG 2000 compressed images over an error-prone wireless network. Though, error protection and correction in wireless image transmission is still a key problem for the multimedia community. In this paper, we propose a joint dynamic error detection for JPEG 2000 encoded image transmission in order to obtain more effective wireless throughput of compressed images. We define an extended code structure to perform joint encoding for transmitters and propose a novel joint error dynamic detection scheme for receivers. An extensive set of simulations was carried out in order to evaluate and demonstrate the performance of our solution, with the proposed method applied to practical CDMA communication systems.
