Journal ArticleDOI
Use of thermal and visible imagery for estimating crop water status of irrigated grapevine
Markus Möller,Victor Alchanatis,Yafit Cohen,M. Meron,J. Tsipris,A. Naor,V. Ostrovsky,M. Sprintsin,Shabtai Cohen +8 more
TL;DR: Parameter variability and robustness of the different CWSI estimates are discussed, and future research should aim at developing thermal imaging into an irrigation scheduling tool applicable to different crops.
Journal ArticleDOI
Estimation of leaf water potential by thermal imagery and spatial analysis
TL;DR: The distribution of LWP in the maps showed that irrigation treatments were better distinguished from each other when the maps were calculated from CWSI than from leaf temperature alone, and the inclusion of the spatial pattern in the classification enhanced the differences between the treatments and was better matched to irrigation amounts.
Journal ArticleDOI
Image fusion of visible and thermal images for fruit detection.
TL;DR: A thermal image and a visible image of an orange canopy scene were fused to improve fruit detection and showed that both image fusion methods improved fruit detection when compared to using the thermal image alone.
Journal ArticleDOI
LAI assessment of wheat and potato crops by VENμS and Sentinel-2 bands
Ittai Herrmann,Agustin Pimstein,Arnon Karnieli,Yuval Cohen,Victor Alchanatis,David J. Bonfil +5 more
TL;DR: In this paper, the authors explored the potential and limitations of using the red-edge spectral bands of the forthcoming superspectral satellites, namely, Vegetation and Environmental New micro Spacecraft (VENμS) and Sentinel-2, for assessing LAI in field crops.
Journal ArticleDOI
Evaluation of different approaches for estimating and mapping crop water status in cotton with thermal imaging
Victor Alchanatis,Yafit Cohen,Shabtai Cohen,Markus Möller,M. Sprinstin,M. Meron,J. Tsipris,Yehoshua Saranga,E. Sela +8 more
TL;DR: In this article, a high-resolution thermal imaging system was used to map crop water status from digital infrared images of the canopy and the effect of time of day on leaf temperature measurements was studied: midday was found to be the optimal time for thermal image acquisition.
