Novel Method to Reconstruct an Image using Hybrid Decomposition

Abstract

Tone mapping method is used for mapping single set of colours to other for simulating the presence of scenes with high dynamic range in a medium with a lower dynamic range. Its primary goal is to generate typicalactive range scene from a maximumactive range scene while preserving the visual information.Other tone mapping techniques divide a picture by base as well as detail layer, then process each distinctly. As a result of the lack of suitable imposement on the two layers, the above approaches may suffer from halo artefacts and over-enhancement. To overcome these issues, we suggest a decomposition of coupled L1 and L0 methods in this study.A piecewise constant effect is achieved throughstriking a l1 sparseness term proceeding base layer to simulate its smoothness quality and a l0 sparsity term through detail layer as a physicalpreceding. On the basis of our layer decomposition approach, we also present a multiscale tone mapping method.For subjective and objective estimations, proposed technique delivers aesthetically engaging consequencesby few halo artefacts when compared to existing tone mapping algorithms, and achieves a higher image quality than previous methods.
