Error accumulation of repetitive image coding

Repetitive image coding is encountered in applications such as video transcoding and image/video servers. This paper studies the effect of error accumulation in repetitive image coding. We describe the conditions under which zero-error-accumulation property holds. We study the impact of intermediate operations (like linear filtering, sealing, and shifting) on image quality in repetitive coding. Experiments with DCT, MC, and MPEG coding algorithms are reported.<
