Recompression of JPEG images by requantization
TL;DR: A novel heuristic for requantizing JPEG images which incorporates the well-known Laplacian distribution of the AC discrete cosine transform coefficients with an analysis of the error introduced by requantization is reported.

A requantization-based method for recompressing JPEG images
TL;DR: A new method for requantizing JPEG images is proposed, based on the well-known Laplacian distribution of the AC discrete cosine transform (DCT) coefficients and on an analysis of the error introduced by requantization.
