JPEG Compatible Coding of High Dynamic Range Imagery using Tone Mapping Operators

چکیده
In this paper, we introduce a new method for compressing high dynamic range (HDR) imageries. Our method exploits the fact that tone mapping is a necessary operation for displaying HDR images on low dynamic range (LDR) reproduction media and seamlessly integrates tone mapping with a well-established image compression standard to produce a HDR image compression technique that is backward compatible with established standards. We present a method to handle color information so that HDR image can be gracefully reconstructed from the tone mapped LDR image and extra information stored with it. We present experimental results to demonstrate that the proposed technique works well and we also discuss future directions of this new research area.

Crowdsourcing evaluation of high dynamic range image compression
Crowdsourcing is becoming a popular cost effective alternative to lab-based evaluations for subjective quality assessment. However, crowd-based evaluations are constrained by the limited availability of display devices used by typical online workers, which makes the evaluation of high dynamic range (HDR) content a challenging task. In this paper, we investigate the feasibility of using low dyna...
متن کاملEffective Compression of High Dynamic Range Images
There's a plenty of file formats designed for storing high dynamic range (HDR) images. But none of them provide satisfactory compression ratio and backward compatibility with existing file formats. In this paper we propose an approach to lossy compressing HDR data in a standard JPEG/JFIF file. An original HDR file is decomposed into a tone mapped version of it LDR (low dynamic range) 24bpp and ...
متن کاملContext-dependent JPEG backward- compatible high-dynamic range image compression
High-dynamic range (HDR) imaging is expected, together with ultrahigh definition and high-frame rate video, to become a technology that may change photo, TV, and film industries. Many cameras and displays capable of capturing and rendering both HDR images and video are already available in the market. The popularity and full-public adoption of HDR content is, however, hindered by the lack of st...
متن کاملA Backward Compatible JPEG Image Coding for High Dynamic Range Image
Recently, the standardization of backward compatible JPEG image coding for high dynamic range image has been undertaken to establish an international standard called JPEG XT. Currently, three profiles called Profiles A, B, and C have been proposed for JPEG XT. Whereas all these profiles perform their image coding in the spatial domain, this paper proposes a new coding approach by manipulating D...
متن کاملModeling a Generic Tone-mapping Operator
Although several new tone-mapping operators are proposed each year, there is no reliable method to validate their performance or to tell how different they are from one another. In order to analyze and understand the behavior of tone-mapping operators, we model their mechanisms by fitting a generic operator to an HDR image and its tone-mapped LDR rendering. We demonstrate that the majority of b...
