Reconstructing High Dynamic Range Image from a Single Low Dynamic Range Image Using Histogram Learning

Applied Sciences
High dynamic range imaging is an important field in computer vision. Compared with general low dynamic range (LDR) images, high dynamic range (HDR) images represent a larger luminance range, making the images closer to the real scene.

Single-Exposure HDR Image Translation via Synthetic Wide-Band Characteristics Reflected Image Training

Mathematics
High dynamic range (HDR) tone mapping techniques have been widely studied to effectively represent the broad dynamic range of real-world scenes. However, generating an HDR image from multiple low dynamic range (LDR) images captured at different exposure ...

Legible Tone Mapping : An evaluation of text processed by tone mapping operators

, 2016
Context. Tone mapping operators (TMO) are designed to reduce the dynamicrange of high dynamic range images so that they can be presented onstandard dynamic range display devices. Many operators focus on creatingperceptually similar images. Objectives. This thesis aims to investigate how dierent TMOs reproducephotographed text.

ADAPTIVE COMPRESSING OF THE HIGH DYNAMIC RANGE OF DIGITAL RADAR SATELLITE IMAGES

Informatika, 2018
Transformation of a digital radar image with a wide dynamic range of luminance values (up to 216 tones) for visualization on a standard monitor is considered. The monitor has 28 gray value range or any of three basic colors in the RGB system.
