A new training strategy for spatial transform networks (STN's)

Navarro Moya, Francisco; Puchalt-Rodríguez, Joan Carles; Layana-Castro, Pablo Emmanuel; García-Garví, Antonio; Sánchez Salmerón, Antonio José (Springer-Verlag, 2022-06)

[EN] Spatial transform networks (STN) are widely used since they can transform images captured from different viewpoints to obtain an objective image. These networks use an image captured from any viewpoint as input and ...
Analysis of a C. elegans lifespan prediction method based on a bimodal neural network and uncertainty estimation

García-Garví, Antonio; Layana-Castro, Pablo Emmanuel; Sánchez Salmerón, Antonio José (Chalmers University of Technology, 2023)

[EN] In recent decades, assays with the nematode Caenorhabditis elegans (C. elegans) have enabled great advances to be made in research on aging. However, performing these assays manually is a laborious task. To solve this ...
Automatic segmentation of Caenorhabditis elegans skeletons in worm aggregations using improved U-Net in low-resolution image sequences

Layana-Castro, Pablo Emmanuel; García-Garví, Antonio; Sánchez Salmerón, Antonio José (Elsevier, 2023-04)

[EN] Pose estimation of C. elegans in image sequences is challenging and even more difficult in low-resolution images. Problems range from occlusions, loss of worm identity, and overlaps to aggregations that are too complex ...
Automation of Caenorhabditis elegans lifespan assay using a simplified domain synthetic image-based neural network training strategy

García-Garví, Antonio; Layana-Castro, Pablo Emmanuel; Puchalt-Rodríguez, Joan Carles; Sánchez Salmerón, Antonio José (Chalmers University of Technology, 2023)

[EN] Performing lifespan assays with Caenorhabditis elegans (C. elegans) nematodes manually is a time consuming and laborious task. Therefore, automation is necessary to increase productivity. In this paper, we propose a ...
Caenorhabditis elegans Multi-Tracker Based on a Modified Skeleton Algorithm

Layana-Castro, Pablo Emmanuel; Puchalt-Rodríguez, Joan Carles; García-Garví, Antonio; Sánchez Salmerón, Antonio José (MDPI AG, 2021-08-20)

[EN] Automatic tracking of Caenorhabditis elegans (C. egans) in standard Petri dishes is challenging due to high-resolution image requirements when fully monitoring a Petri dish, but mainly due to potential losses of ...
Desarrollo de técnicas avanzadas de seguimiento de posturas para reconocimiento de comportamientos de C. elegans

Layana Castro, Pablo Emmanuel (Universitat Politècnica de València, 2023-10-26)

[ES] El objetivo principal de esta tesis es el desarrollo de técnicas avanzadas de seguimiento de posturas para reconocimiento de comportamientos del Caenorhabditis elegans o C. elegans. El C. elegans es una clase de ...

Layana Castro, Pablo Emmanuel (Universitat Politècnica de València, 2018-11-19)

El trabajo a realizar pretende desarrollar una aplicación automática de visión, la cuál consistirá en capturar imágenes en tiempo real de placas de Petri, realizar un pre-procesamiento de la misma usando un raspberry pi, ...
Diseño, implementación y evaluación de un sistema de visión por computador basado en visión artificial con técnicas tradicionales y arquitecturas de redes neuronales para el análisis de segmentación y la detección de defectos en naranjas.

Sandoval Salvatierra, Misael Reinaldo (Universitat Politècnica de València, 2022-11-07)

[ES] Este trabajo consistirá en diseñar, implementar y evaluar diferentes técnicas tanto tradicionales como con arquitecturas de redes neuronales artificiales de visión por computador para segmentar los defectos de las ...
Improving skeleton algorithm for helping Caenorhabditis elegans trackers

Layana-Castro, Pablo Emmanuel; Puchalt-Rodríguez, Joan Carles; Sánchez Salmerón, Antonio José (Nature Publishing Group, 2020-12-17)

[EN] One of the main problems when monitoring Caenorhabditis elegans nematodes (C. elegans) is tracking their poses by automatic computer vision systems. This is a challenge given the marked flexibility that their bodies ...
Reducing Results Variance in Lifespan Machines: An Analysis of the Influence of Vibrotaxis on Wild-Type Caenorhabditis elegans for the Death Criterion

Puchalt-Rodríguez, Joan Carles; Layana-Castro, Pablo Emmanuel; Sánchez Salmerón, Antonio José (MDPI AG, 2020-11)

[EN] Nowadays, various artificial vision-based machines automate the lifespan assays of C. elegans. These automated machines present wider variability in results than manual assays because in the latter worms can be poked ...
Skeletonizing Caenorhabditis elegans Based on U-Net Architectures Trained with a Multi-worm Low-Resolution Synthetic Dataset

Layana-Castro, Pablo Emmanuel; García-Garví, Antonio; Navarro Moya, Francisco; Sánchez Salmerón, Antonio José (Springer-Verlag, 2023-09)

[EN] Skeletonization algorithms are used as basic methods to solve tracking problems, pose estimation, or predict animal group behavior. Traditional skeletonization techniques, based on image processing algorithms, are ...
