|| Image & Video Communications: Source/channel coding|
|| COMBINED ERROR PROTECTION AND COMPRESSION WITH TURBO CODES FOR IMAGE TRANSMISSION USING A JPEG2000-LIKE ARCHITECTURE|

|| In this paper, a joint source channel coding scheme for error resilient image transmission is proposed. Instead of compressing the image using the classical entropy coder, the redundancy of the image is exploited by using turbo codes for both data compression and error protection. At the decoder, the bit-planes are reconstructed in sequence by a multistage decoder. By properly choosing rate and puncturing, the system is able to approach the limit theoretically attainable and to outperform the separated approach of a JPEG2000 compressed image and the best turbo codes for the same overall length.|
