Local and Global Tone Mapping Operators in HDR Image Processing with Amalgam Technique
High Dynamic range HDR images are achieved even in mobile phone, due to the recent advances in the field of HDR. Tone mapping operator converts the HDR image into LDR images which can be visualized clearly There are various operators available in the HDR tool box In. this paper we have demonstrated the all the tone mapping operators dividing them as local and global as given in the early literature studies. The various results of the operators are shown in the paper with the subjective analysis. A new hybrid method is proposed with local and global operator and the evaluation is done. By examining all the combination of the operators the global combination with the same global method gives a promising result. Compared with the individual local and global tone mapping operators the combinational hybrid operator gives a better performance.
