Automatic detection of skin defects in citrus fruits using a multivariate image analysis approach

López García, Fernando; Andreu García, Gabriela; Blasco Ivars, José; Aleixos Borrás, María Nuria; Valiente González, José Miguel (Elsevier, 2010-05)

One of the main problems in the post-harvest processing of citrus is the detection of visual defects in order to classify the fruit depending on their appearance. Species and cultivars of citrus present a high rate of ...
Automatic pollen recognition using convolutional neural networks: The case of the main pollens present in Spanish citrus and rosemary honey

Valiente González, José Miguel; Juan-Borras, María del Sol; López García, Fernando; Escriche Roberto, Mª Isabel (Elsevier, 2023-10)

[EN] The automation of honey pollen visual sorting overcomes the limitations of the conventional procedure helping the specialist in this time-consuming task. In this work, a novel and comprehensive Ground Truth of almost ...
Classification of Honey Pollens with ImageNet Neural Networks

López García, Fernando; Valiente González, José Miguel; Escriche Roberto, Mª Isabel; Juan-Borras, María del Sol; Visquert Fas, Mario; Atienza-Vanacloig, Vicente; Agustí-Melchor, Manuel (Springer-Verlag, 2023)

[EN] The classification of honey pollen grains is performed in order to clas- sify honey according to its botanical origin, which is of great importance in terms of marketing. This visual work is currently done by human ...
Desarrollo de un sistema cognitivo de visión para la navegación robótica

Aracil López, Rafael (Universitat Politècnica de València, 2012-09-07)

El proyecto no trata de la obtención de puntos característicos, trata de la navegación robótica o la navegación de un robot. Para ello se utiliza la obtención de puntos característicos en los frames para reconocer la parte ...
Desarrollo de una red neuronal convolucional (CNN) para la distinción de variedades de pólenes en muestras de miel

Martín Osuna, Juan José (Universitat Politècnica de València, 2024-02-14)

[ES] El presente proyecto tiene como objetivo el desarrollo de una nueva arquitectura de Red neuronal convolucional (CNN) para el proyecto ¿Polenet¿, así como su posterior estudio de comportamiento con distintos datasets ...
Detection of visual defects in citrus fruits: multivariate image analysis vs graph image segmentation

López García, Fernando; Andreu García, Gabriela; Valiente González, José Miguel; Atienza Vanacloig, Vicente Luis (Springer Verlag (Germany), 2013)

This paper presents an application of visual quality control in orange post-harvesting comparing two different approaches. These approaches correspond to two very different methodologies released in the area of Computer ...

Peinado Sanchis, Felipe Ignacio (Universitat Politècnica de València, 2015-09-29)

[ES] En este trabajo se evalúa la viabilidad de un sistema automático de clasificación de pólenes en imágenes de miel obtenidas con microscopio basado en un modelo que usa como discriminantes atributos derivados del ...
Real-time surface grading of ceramic tiles

López García, Fernando (Universitat Politècnica de València, 2008-05-06)

This thesis presents a case of study of the development and performance analysis of a surface grading application with real-time compliance. We address the issue of spatial and temporal uniformity in the acquisition ...
Segmentation techniques in image analysis: A comparative study

Vitale, Raffaele; Prats-Montalbán, José Manuel; López García, Fernando; BLASCO IVARS, JOSE; Ferrer, Alberto (John Wiley & Sons, 2016-12)

[EN] Nowadays, the detection, localization, and quantification of different kinds of features in an RGB image (segmentation) is extremely helpful for, e.g., process monitoring or customer product acceptance. In this ...
Vision-based discrimination of tuna individuals in grow-out cages through a fish bending model

Atienza-Vanacloig, Vicente; Andreu García, Gabriela; López García, Fernando; Valiente González, José Miguel; Puig Pons, Vicente (Elsevier, 2016-11-15)

This paper proposes a robust deformable adaptive 2D model, based on computer vision methods, that automatically fits the body (ventral silhouette) of Bluefin tuna while swimming. Our model (without human intervention) ...
