Abstract

The paper comprises study on accumulation of errors produced by near-lossless JPEG-LS in the consecutive compression-decompression cycles. Paper proves that alternatively, lossless compression can be performed on luminance and chrominance with reduced representation bit numbers. The advantage is that the errors do not accumulate in the consecutive cycles of compression because rounding errors of the RGB → YCRCB →RGB transformation do not accumulate in the consecutive transformation cycles. Exemplary experimental data that verify these statements are included in the paper.
