Survey on Implementation and Analysis of Power-Constrained Contrast Enhancement Algorithm Using a Sub-band Decomposed MSR for OLED Display

Pallavi Ghormade, S. K. Bhatia

Abstract: Among all the displays available, organic light emitting diode (OLED) are the most promising displays. They do not require backlight as required to LCDs. For any picture to be human observable, the contrast should be well adjusted. Also, for any display it is more sufficient to use if it consumes less power. In this paper, various image enhancement techniques used for images are discussed. The techniques are histogram equalization, histogram modification, power constrained contrast enhancement, lightness and retinex theory, center/surround retinex, multiscale retinex, sub-band decomposed multiscale retinex, contrast enhancement using dynamic stochastic resonance, non-linear multiscale enhancement. Also, the power model for emissive displays is also discussed and the outlook of the power constrained contrast algorithm using sub-band decomposed MSR is discussed.

Keywords: Power consumption, contrast enhancement, OLED, sub-band decomposition, multi-scale retinex
