An Adaptive Clear High-Dynamic Range Fusion Algorithm Based on Field-Programmable Gate Array for Real-Time Video Stream [PDF]
SensorsConventional High Dynamic Range (HDR) image fusion algorithms generally require two or more original images with different exposure times for synthesis, making them unsuitable for real-time processing scenarios such as video streams.

Human Visual System Model-Based Optimized Tone Mapping of High Dynamic Range Images
IEEE Access, 2021 High dynamic range (HDR) image and video technology can provide significant picture quality improvement over the standard dynamic range (SDR). However, when HDR content is represented on an SDR display, dynamic range compression may result in image ...

Single Exposure High Dynamic Range Image Reconstruction Based on Deep Dual-Branch Network
IEEE Access, 2021 In this article, we relate the operation of single-frame-based high dynamic range (HDR) image reconstruction to the following two tasks: 1) highlight suppression in over-exposed areas and 2) noise elimination in under-exposed areas.

HDR-GAN: HDR Image Reconstruction From Multi-Exposed LDR Images With Large Motions [PDF]
IEEE Transactions on Image Processing, 2021 Synthesizing high dynamic range (HDR) images from multiple low-dynamic range (LDR) exposures in dynamic scenes is challenging. There are two major problems caused by the large motions of foreground objects. One is the severe misalignment among the LDR images. The other is the missing content due to the over-/under-saturated regions caused by the moving

Effective despeckling of HDR images [PDF]
SIGGRAPH Asia 2011 Sketches, 2011 High Dynamic Range (HDR) images are common in computer graphics. In these images, speckles can appear for various reasons, such as high variance for Monte-Carlo-based rendering engines. These speckles are responsible for large artefacts if non-robust post-processing methods are used, such as tonemapping operators relying on a maximal or average ...
