Tone-mapping high dynamic range images by novel histogram adjustment
نویسندگان
چکیده
In this paper, we present novel histogram adjustment methods for displaying high dynamic range image. We first present a global histogram adjustment based tone mapping operator, which well reproduces global contrast for high dynamic range images. We then segment images and carry out adaptive contrast adjustment using our global tone mapping operator in the local regions to reproduce local contrast and ensure better quality. We demonstrate that our methods are fast, easy to use and a fixed set of parameter values produce good results for a wide variety of images. & 2009 Elsevier Ltd. All rights reserved.

Progressive color transfer for images of arbitrary dynamic range
Image manipulation takes many forms. A powerful approach involves image adjustment by example. To make color editsmore intuitive, the intelligent transfer of a user-specified target image’s color palette can achieve a multitude of creative effects, provided the user is supplied with a small set of straightforward parameters. We present a novel histogram reshaping technique which allows signific...
متن کاملPseudo Hdr Video Using Inverse Tone Mapping
In the Pseudo-Multiple-Exposure-Based Tone Fusion with Local Region Adjustment [1], it introduces a framework for inverse tone mapping which uses only one Low Dynamic Range (LDR) image to evaluate High Dynamic Range (HDR) image. First, map LDR image to HDR images using S curve. By changing the parameters of S curve, we can get different EV scenes. Then, segment the image into four different lum...
متن کاملTone mapping appropriate for specific images using brightness and histogram modification
This paper proposes an algorithm that can improve performance by searching for tone mapping optimized for three types of images through image analysis while maintaining a tone mapping shape based on human visual characteristics. The algorithm uses the optimized Retinex-based color restoration technique by analyzing three types of images based on luminance: highand low-luminance images and image...
متن کاملA Hybrid Tone Mapping for High Dynamic Range Images
In this study, low dynamic range images were produced from high dynamic range images using hybrid tone mapping. Firstly, high dynamic range images were constructed from the series of images by varying exposure through an image fusion method. Then the high dynamic range images were mapped into 8 bit images using hybrid tone mapping. Our approach is based on combination of luminance map and bilat...
متن کاملStructural Fidelity vs. Naturalness - Objective Assessment of Tone Mapped Images
There has been an increasing number of tone mapping algorithms developed in recent years that can convert high dynamic range (HDR) to low dynamic range (LDR) images, so that they can be visualized on standard displays. Nevertheless, good quality evaluation criteria of tone mapped images are still lacking, without which, different tone mapping algorithms cannot be compared and there is no meanin...
