Efficient Generalized Colored image Enhancement
Syed Mashhood Murtaza, Jahanzeb Ahmad, Usman Ali · 2006
Hue preservation is an essential requirement for color image enhancement, but preserving hue introduces the gamut problem. A fast technique is proposed which can be applied to generalize any linear or non-linear gray-scale contrast enhancement function to the color domain. The technique provides hue preserved, gamut problem free color contrast enhancement in accordance with the gray-scale contrast enhancing function it generalizes. Results for the proposed color image enhancement technique are better than the currently available techniques
