摘要

In this work we explore possibilities for coding and decoding tailor made for image transmission. To do so, we introduce a loss function that expresses the overall performance of a coding scheme for discrete channels and exchange the usual goal of minimizing the error probability to that of minimizing the expected loss. In this environment we explore the possibilities of using poset-decoders to make a message-wise unequal error protection (UEP), where the most valuable information is protected by placing in its proximity information words that differ by small valued information. We give explicit examples, done for scale-of-gray images, including visual simulations for the BSMC.
