REALISTIC HDR TONE-MAPPING BASED ON CONTRAST PERCEPTION MATCHING

Dr. A. Senthil Arumugam, D. Paulin Diana Dani

Abstract :

In this paper, a new method to measure human’s reaction time on local contrast is introduced. It is believed the reac– tion time is highly correlated with the response strength on local contrasts in human visual system. Using the proposed method, a large set of subjective viewing data were then col– lected, and a full–range (from near–threshold to suprathresh– old) contrast perception model on low dynamic range dis– play is built. Based on the proposed model and Plainis’ reac– tion time model [17], a new realistic tone–mapping operator, which minimizes the perception difference of local contrasts between HDR and LDR images, is proposed. Experimental results conﬁrmed the performance of the proposed operator
