Impact of Tone Mapping in High Dynamic Range Image Compression
Tone mapping or range reduction is often used in High Dynamic Range (HDR) visual signal compression to take advantage of the existing image/video coding architectures. Thus, it is important to study the impact of tone mapping on the visual quality of decompressed HDR visual signals. To our knowledge, most of the existing studies focus only on the quality loss in the resultant low dynamic range ...
متن کاملCrowdsourcing 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 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 کاملHigh Dynamic Range Image and Video Data Compression
Although high dynamic range (HDR) image and video are becoming common in many computer graphics applications, their data compression has received little attention so far. In this paper, we propose a practical approach to HDR video compression for efficient storage and fast transmission. Most current HDR images and videos are created from multiple exposures of the scene with varying exposures or...
متن کاملHigh Dynamic Range Image with Two Exposures
In related work, most algorithms generate high dynamic range image by fusing several differently exposed images. In this paper, we propose an image fusion pipeline that generates a high dynamic range image by fusing longand short-exposure raw images. Some algorithms generating high dynamic range image with two exposure images may incur artifacts. Our method uses the property of raw image to ove...
