Visible and Near-Infrared Image Acquisition and Fusion for Night Surveillance
Chemosensors, 2021 Image fusion combines images with different information to create a single, information-rich image. The process may either involve synthesizing images using multiple exposures of the same scene, such as exposure fusion, or synthesizing images of ...

Hierarchical tone mapping based on image colour appearance model
IET 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

Deep Reformulated Laplacian Tone Mapping
CoRR, 2021 Wide dynamic range (WDR) images contain more scene details and contrast when compared to common images. However, it requires tone mapping to process the pixel values in order to display properly. The details of WDR images can diminish during the tone mapping process.
