Variations of Images to Increase Their Visibility [PDF]

International Journal of Sciences, 2013
The calculus of variations applied to the image processing requires some numerical models able to perform the variations of images and the extremization of appropriate actions. To produce the variations of images, there are several possibilities based on the brightness maps.

Learning to compare visibility on webcam images [PDF]

Proceedings of the 10th International Conference on Climate Informatics, 2020
Since the 2000’s, cameras are considered as an interesting source of opportunistic meteorological data. This short study deals with the comparison of visibility, in a meteorological sense, between images. A new dataset has been built from publicly available webcam sequences.

Automatic detection of regions in spinach canopies responding to soil moisture deficit using combined visible and thermal imagery [PDF]

, 2014
Thermal imaging has been used in the past for remote detection of regions of canopy showing symptoms of stress, including water deficit stress. Stress indices derived from thermal images have been used as an indicator of canopy water status, but these ...

Visibility Restoration in Infra-Red Images

2020 25th International Conference on Pattern Recognition (ICPR), 2021
For the last decade, single image defogging has been a subject of interest in image processing. In the visible spectrum, fog and haze decrease the visibility of distant objects. Thus, the objective of the visibility restoration is to remove as much as possible the effect of the fog within the image. Infrared sensors are more and more used in automotive

AEFusion: Adaptive Enhanced Fusion of Visible and Infrared Images for Night Vision

Remote Sensing
Under night vision conditions, visible-spectrum images often fail to capture background details. Conventional visible and infrared fusion methods generally overlay thermal signatures without preserving latent features in low-visibility regions.

Infrared and Visible Image Fusion Based on Autoencoder Composed of CNN-Transformer

IEEE Access, 2023
Image fusion model based on autoencoder network gets more attention because it does not need to design fusion rules manually. However, most autoencoder-based fusion networks use two-stream CNNs with the same structure as the encoder, which are unable to ...
