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 ...

Imaging from STIX visibility amplitudes [PDF]

Astronomy & Astrophysics, 2021
Aims.This study is aimed at providing the first demonstration of STIX Fourier-transform X-ray imaging using semi-calibrated (amplitude-only) visibility data acquired during Solar Orbiter’s cruise phase.Methods.We used a parametric imaging approach whereby STIX visibility amplitudes are fitted by means of two non-linear optimization methods: a fast meta-

MVF: A Novel Infrared and Visible Image Fusion Approach Based on the Morphing Convolutional Structure and the Light-Weight Visual State Space Block

IEEE Access
Image/feature decomposition plays a crucial role in image fusion tasks. However, in deep learning-based fusion methods, existing decomposition operations tend to be either overly simplistic or excessively intricate to learn effectively.

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 ...

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

An Enhanced Image Fusion Algorithm by Combined Histogram Equalization and Fast Gray Level Grouping Using Multi-Scale Decomposition and Gray-PCA

IEEE Access, 2020
Image enhancement is a challenging task in image analysis particularly, it is more challenging in performing image fusion. Image fusion is the process of combining multiple images to produce quality output without any variation in contrast, blurring, and
