Sarabia, Ricardo; Aquino Martín, Arturo
; Ponce Real, Juan Manuel; López, Gilberto; Andújar Márquez, José Manuel (MDPI, 2020-02)
Within the context of precision agriculture, goods insurance, public subsidies, fire damage assessment, etc., accurate knowledge about the plant population in crops represents valuable information. In this regard, the ... -
Automatic Counting and Individual Size and Mass Estimation of Olive-Fruits Through Computer Vision Techniques
Ponce Real, Juan Manuel; Aquino Martín, Arturo; Millán Prior, Borja; Andújar Márquez, José Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2019-05)
Fruit grading is an essential post-harvest task in the olive industry, where size-and-mass based fruit classi cation is especially important when processing high-quality table olives.Within this context, this research ... -
Computer Vision in Oliviculture. Contributions to the Postharvest Estimation of Individual Fruit Features, Early In-the-field Yield Prediction, and Individual Tree Characterisation from Aerial Imagery, by means of Image Analysis
(Universidad de Huelva, 2020)Actualmente, el cultivo del olivo (Olea europaea) ocupa una importante posición dentro de la actividad agrícola a nivel internacional. Sin embargo, a pesar de sus volúmenes de producción, y de la dimensión del mercado ... -

Olive-Fruit Mass and Size Estimation Using Image Analysis and Feature Modeling
Ponce Real, Juan Manuel; Aquino Martín, Arturo; Millán Prior, Borja; Andújar Márquez, José Manuel (MDPI, 2018-09)
This paper presents a new methodology for the estimation of olive-fruit mass and size, characterized by its major and minor axis length, by using image analysis techniques. First, different sets of olives from the varieties ... -
Vineyard pruning weight assessment by machine vision: towards an on-the-go measurement system
Millán Prior, Borja; Diago, María Paz; Aquino Martín, Arturo; Palacios, Fernando; Tardaguila, Javier (International Viticulture and Enology Society (IVES), 2019)
Aim: Pruning weight is an indicator of vegetative growth and vigour in grapevine. Traditionally, it is manually determined, which is time-consuming and labour-demanding. This study aims at providing a new, non-invasive and ...
