Abstract

Background: In Recent years Display of HDR images on yardstick LDR Displays with Tone mapping Operators (TMO) has many issues like halo artefacts, edge preservations and visual appearance. Always there exists a issue about usage of operator with regard to the input sequence without all these factors. Objectives: In this paper a thorough analysis is carried out with 31 TMO operators. Existing study papers are up to maximum of 8 TMOs, but this paper evaluates all the 31 operators and the objective quality measure is calculated. Researchers are carried out to identify a better operator for its own applications, which motivated to do this paper, the resultant analysis provokes to the development of a new method with lesser computational time. This work can be further extended to optimization of the algorithm used in fusion of base and detail layers of sequence of input. From the analysis the naturalness, structural fidelity and Quality of the image can be improved.
