Hardware Implementation of an Automatic Rendering Tone Mapping Algorithm for a Wide Dynamic Range Display

open access: yesJournal of Low Power Electronics and Applications, 2013
Tone mapping algorithms are used to adapt captured wide dynamic range (WDR) scenes to the limited dynamic range of available display devices. Although there are several tone mapping algorithms available, most of them require manual tuning of their ...

Scene-based imperceptible-visible watermarking for HDR video content [PDF]

open access: yes, 2019
This paper presents the High Dynamic Range - Imperceptible Visible Watermarking for HDR video content (HDR-IVW-V) based on scene detection for robust copyright protection of HDR videos using a visually imperceptible watermarking methodology.

HUNGARIAN SENTENCE INTONATION [PDF]

open access: yes, 1988
this paper differs from the usual mechanisms like Tone Mapping (Williams 1971), Well-Formedness Conditions (Goldsmith 1976), etc. essentially only in having this `once only' property.

A 148dB focal-plane tone-mapping QCIF imager [PDF]

open access: yes, 2012
http://digital.csic.es/handle/10261/84304This paper presents a QCIF HDR imager where visual information is simultaneously captured and adaptively compressed by an in-pixel tone-mapping scheme [1].

Live demonstration: Real-time high dynamic range video acquisition using in-pixel adaptive content-aware tone mapping compression [PDF]

open access: yes, 2015
This demonstration targets the acquisition of realtime video sequences involving High Dynamic Range (HDR) scenes. Adaptation to different illumination conditions while preserving contrast is achieved by using a sensor chip, which implements an adaptive ...

Low-illumination image enhancement with logarithmic tone mapping

open access: yesOpen Computer Science, 2023
For low-illumination video sequences, some existing enhancement algorithms have some problems, such as image over-enhancement, color distortion, and inadequate detail processing.

Hierarchical tone mapping based on image colour appearance model

open access: yesIET Computer Vision, 2014
To solve the problem of low efficiency and poor effect of the current tone mapping methods for the high dynamic range images, the authors propose a hierarchical tone mapping algorithm based on colour appearance model. The discrete Gaussian kernel is used

Extending and Matching a High Dynamic Range Image from a Single Image

open access: yesSensors, 2020
Extending the dynamic range can present much richer contrasts and physical information from the traditional low dynamic range (LDR) images. To tackle this, we propose a method to generate a high dynamic range image from a single LDR image. In addition, a

A local tone mapping operator for high dynamic range images [PDF]

open access: yes, 2011
In this paper, we present a new tonemapping operator to display high dynamic range image onto conventional displayable devices and printers. In our work, a new tone map algorithm, derived from the Contrast Limited Adaptive histogram Equalization (CLAHE ...
