Single Image LDR to HDR Conversion Using Conditional Diffusion

International Conference on Information Photonics, 2023
Digital imaging aims to replicate realistic scenes, but Low Dynamic Range (LDR) cameras cannot represent the wide dynamic range of real scenes, resulting in under-/overexposed images.

Unsupervised Optical Flow Estimation for Differently Exposed Images in LDR Domain

IEEE transactions on circuits and systems for video technology (Print), 2023
Differently exposed low dynamic range (LDR) images are often captured sequentially using a smart phone or a digital camera with movements. Optical flow thus plays an important role in ghost removal for high dynamic range (HDR) imaging.

Neural Augmentation-Based Saturation Restoration for LDR Images of HDR Scenes

IEEE Transactions on Instrumentation and Measurement, 2023
There are shadow and highlight regions in a low-dynamic-range (LDR) image which is captured from a high-dynamic-range (HDR) scene. It is an ill-posed problem to restore the saturated regions of the LDR image. In this article, the saturated regions of the

HDR-cGAN: single LDR to HDR image translation using conditional GAN

Indian Conference on Computer Vision, Graphics & Image Processing, 2021
The prime goal of digital imaging techniques is to reproduce the realistic appearance of a scene. Low Dynamic Range (LDR) cameras are incapable of representing the wide dynamic range of the real-world scene.

Compression efficiency of HDR/LDR content

2015 Seventh International Workshop on Quality of Multimedia Experience (QoMEX), 2015
High Dynamic Range (HDR) imaging is capable of delivering a wider range of luminance and color gamut compared to Standard Dynamic Range (SDR), offering to viewers a visual quality of experience close to that of real-life. In this study, we evaluate the quality of coded original HDR streams and HDR streams reconstructed from SDR videos and metadata ...

Calibration of multiple LDR brachytherapy sources

Medical Physics, 2006
A trend is underway toward the use of prepackaged low dose rate brachytherapy sources, which come in the form of strands, coiled line sources, preloaded needles, and sterile cartridge packs. Since the medical physicist is responsible for verification of source strength prior to patient treatment, development of prepackaged source strength verification ...
