Color enhancement in the compressed domain
Jayanta Mukhopadhyay, Sanjit K. Mitra · 2008
This paper presents a new efficient technique for color enhancement in the compressed domain. In the proposed technique the enhancement computation is performed in three steps, namely, adjustment of dynamic range of brightness values, preservation of local contrast and preservation of color with all computations involving scaling of the DCT coefficients. Further special care has been taken for reducing the blocking artifacts. The proposed algorithm provide better performances compared to some of the existing techniques in the compressed domain.
