摘要

Noisy channels have significant influence on the quality of image transmission as the error rates increase and a degrading affect at higher error rates. This paper presents a recovery scheme for image transmission over noisy channels based on a hybrid transform and error correcting codes with error replacement strategy. In this paper we describe allocating redundant bits based on some importance metrics. In addition, it describes in details the ECC and the used transforms. The effects of errors are measured and examined which show that are our scheme is robust for protecting image transmission over noisy channel and minimizes visual effects when compared with a single transform. The also paper describes the implementation of the recovery scheme and details the findings of our evaluation on the transforming choices.
