To achieve high quality perception based on multi scale retinex algorithm using PCCE mechanism for OLED devices

Abstract

The power constrained contrast enhancement algorithm is used for emissive displays and it is based  on histogram equalization. However, with HE-based contrast enhancement there is an inherent risk of  overstretching. To avoid this we presents a high equipped power constrained algorithm for OLEDs based on multi scale retinex. MSR plays main role in the proposed algorithm and it is based on of power controllable log operation fallowed by sub band wise gain control. The MSR is used for power reduction in display of images, the same approach can be used for high definition videos, and the algorithm provides enhanced video sequence, better perceptual video quality and power consistent ratio without flickering artifacts. This proposed algorithm gives the better visual quality than previous existed power constrained contrast enhancement algorithm for videos.
