LDR Image for Suitable Display in Conventional Display Devices by CIELAB based Tone-Mapping Algorithm

Clustering Based Local Tone Mapping Algorithm for Displaying Hdr Images on Ldr Devices

In order to display HDR (High Dynamic Range) images with increased dynamic range on LDR (Low Dynamic Range) monitors, it is necessary to perform a tone mapping technique, which is a process of compressing a dynamic range of an image. Representative techniques are global tone mapping and local tone mapping. Though global tone mapping is simple to compute, it has low local contrast and loses deta...

Image Retargeting for Small Display Devices

In this paper, we propose a novel image importance model for image retargeting. The most widely used image importance model in existing image retargeting methods is L1-norm or L2-norm of gradient magnitude. It works well under non-complex environment. However, the gradient magnitude based image importance model often leads to severe visual distortions when the scene is cluttered or the backgrou...

Image Tone Mapping for an HDR Image by Adoptive Global tone-mapping algorithm

It is the age of fast and good quality Digital images, those are subject to blurring due to many hardware limitations, such as atmospheric disturbance, apparatus noise and poor focus quality. Visual saliency aims to predict the attentional steady intent look of observers viewing a scene, and therefore tone mapping of high dynamic range (HDR) images concept is highly useful for it. The work has ...

A Multicurve Tone Mapping Operator for the Display of High Dynamic Range Image and Video

This paper presents a novel method for tone mapping high dynamic range images and videos for display in conventional low dynamic range devices. The new multi-curve method uses tone mapping curves that are adaptive to local luminance levels. The new method has the computational simplicity of curve based tone mapping methods and achieves results comparable to spatial operator methods. When applyi...
