...Unlike, the existing SPS based [9] - [10] algorithms, proposed algorithm only needs to send lossy JPEG2000 encoded image and residual image (e) at the decoder side. e = P − P̂ (5) The near-lossless mode can be enabled by simply quantizing the residual error (e) and using the reconstructed pixels (P̃ ) for the prediction of the future pixels. ê = ⎧⎨ ⎩ ⌊ e+Δ 2Δ+1 ⌋ e ≥ 0⌊ e−Δ 2Δ+1 ⌋ e < 0 (6) Here, Δ controls the trade-off between the compression ratio and the distortion in such a way that |...
