Fruit sizing using AI: A review of methods and challenges
(Elsevier, 2023-09-23)
Fruit size at harvest is an economically important variable for high-quality table fruit production in orchards and vineyards. In addition, knowing the number and size of the fruit on the tree is essential ...
Looking behind occlusions: A study on amodal segmentation for robust on-tree apple fruit size estimation
(Elsevier, 2023-04-21)
The detection and sizing of fruits with computer vision methods is of interest because it provides relevant information to improve the management of orchard farming. However, the presence of partially ...
Observation and assessment of model retrievals of surface exchange components over a row canopy using directional thermal data
(Institute of Electrical and Electronics Engineers, 2023-07-21)
Land surface temperature is an essential climate variable that can serve as a proxy for detecting water deficiencies in croplands and wooded areas. Its measurement can however be influenced by anisotropic ...
Evaluation of transpiration in different almond production systems with two-source energy balance models from UAV thermal and multispectral imagery
(Springer, 2023-10-31)
A growing number of intensive irrigated production systems of the almond crop have been established in recent years. However, there is little information regarding the crop water requirements. Remote ...
Viticulture adaptation to global warming: Modelling gas exchange, water status and leaf temperature to probe for practices manipulating water supply, canopy reflectance and radiation load
(Elsevier, 2023-01-31)
Associated with climate change, the frequency, duration, and intensity of heatwaves are increasing in most of the key wine regions worldwide. Depending on timing, intensity, and duration, heatwaves can ...
Assessing automatic data processing algorithms for RGB-D cameras to predict fruit size and weight in apples
(Elsevier, 2023-10-07)
Data acquired using an RGB-D Azure Kinect DK camera were used to assess different automatic algorithms to estimate the size, and predict the weight of non-occluded and occluded apples. The programming ...
Accurate estimates of land surface energy fluxes and irrigation requirements from UAV-based thermal and multispectral sensors
(Elsevier, 2023-03-28)
The two-source energy balance model estimates canopy transpiration (Tr) and soil evaporation (E) traditionally from satellite partitions of remotely sensed land surface temperature (LST) and the ...
Differential response to calcium-labelled (44Ca) uptake and allocation in two peach rootstocks in relation to transpiration under in vitro conditions
(Elsevier, 2023-11-28)
Calcium-labelled (44Ca) uptake and transport under in vitro GreenTray® temporary immersion bioreactor conditions have been studied related to aeration conditions. For this aim, Rootpac®-20 (RP-20) and ...
Simultaneous fruit detection and size estimation using multitask deep neural networks
(Elsevier, 2023-08-06)
The measurement of fruit size is of great interest to estimate the yield and predict the harvest resources in advance. This work proposes a novel technique for in-field apple detection and measurement ...
Estimating multi-scale irrigation amounts using multi-resolution soil moisture data: A data-driven approach using PrISM
(Elsevier, 2023-11-22)
Irrigated agriculture is the primary driver of freshwater use and is continuously expanding. Precise knowledge of irrigation amounts is critical for optimizing water management, especially in semi-arid ...
