To　improve　the　quality　of　images　in　image　communication　system　over　error　prone　channels,　a　multiple　description　coding　(MDC)　algorithm　based　on　region　of　interest　(ROI)　by　using　redundant　transform　is　proposed.　Due　to　the　independence　of　the　transformed　coefficients,　redundant　transform　is　combined　with　JPEG　coding　system　o　generate　multiple　descriptions.　The　number　and　choice　of　projections　can　be　changed　freely　for　the　demand　of　encoding　redundancy.　To　achieve　better　reconstructed　image　quality,　the　region　of　interest　is　taken　into　account.　Experimental　results　show　that　the　proposed　algorithm　is　simply　implemented　and　easier　to　extend　than　other　MDC　methods.　It　can　improve　the　visual　quality　of　the　ROI.
