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 ...
Active backlight for automating visual monitoring: An analysis of a lighting control technique for Caenorhabditis elegans cultured on standard Petri plates

Puchalt-Rodríguez, Joan Carles; Sánchez Salmerón, Antonio José; Martorell Guerola, Patricia; Genovés Martínez, Salvador (Public Library of Science, 2019-04-16)

[EN] Lifespan and healthspan machines can undergo C. elegans image segmentation errors due to changes in lighting conditions, which produce non-uniform images. Most C. elegans monitoring machines use backlight techniques ...
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 ...
Development and Evaluation of New Methods for Automating Experiments with C. Elegans Based on Active Vision

Puchalt Rodríguez, Joan Carles (Universitat Politècnica de València, 2022-03-10)

[ES] Esta tesis se centra en el desarrollo de nuevas técnicas automatizadas que permiten inspeccionar nematodos Caenorhabidits elegans (C. elegans) en placas de Petri estándar, para el análisis de sus comportamientos. C. ...
Diseño de un prototipo para seguimiento de la trazabilidad y control de lotes de producción mediante cámara de visión Cognex

Serrano Durá, Rafael (Universitat Politècnica de València, 2023-06-13)

[ES] El presente trabajo de fin de grado titulado “Diseño de un prototipo para seguimiento de la trazabilidad y control de lotes de producción mediante cámara de visión Cognex” plantea un prototipo de aplicación industrial, ...
Improving lifespan automation for Caenorhabditis elegans by using image processing and a post-processing adaptive data filter

Puchalt-Rodríguez, Joan Carles; Sánchez Salmerón, Antonio José; Ivorra Martínez, Eugenio; Genovés Martínez, Salvador; Martínez, Roberto; Martorell Guerola, Patricia (Nature Publishing Group, 2020-05-26)

[EN] Automated lifespan determination for C. elegans cultured in standard Petri dishes is challenging. Problems include occlusions of Petri dish edges, aggregation of worms, and accumulation of dirt (dust spots on lids) ...
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 ...
Multiview motion tracking based on a cartesian robot to monitor Caenorhabditis elegans in standard Petri dishes

Puchalt-Rodríguez, Joan Carles; González-Rojo, José F.; Gómez-Escribano, Ana Pilar; Vázquez-Manrique, Rafael P.; Sánchez Salmerón, Antonio José (Nature Publishing Group, 2022-02-02)

[EN] Data from manual healthspan assays of the nematode Caenorhabditis elegans (C. elegans) can be complex to quantify. The first attempts to quantify motor performance were done manually, using the so-called thrashing or ...
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 ...
Small flexible automated system for monitoring Caenorhabditis elegans lifespan based on active vision and image processing techniques

Puchalt-Rodríguez, Joan Carles; Sánchez Salmerón, Antonio José; Ivorra, Eugenio; Llopis, Silvia; Martínez, Roberto; Martorell, Patricia (Nature Publishing Group, 2021-06-10)

[EN] Traditionally Caenorhabditis elegans lifespan assays are performed by manually inspecting nematodes with a dissection microscope, which involves daily counting of live/dead worms cultured in Petri plates for 21-25 ...
Towards Lifespan Automation for Caenorhabditis elegans Based on Deep Learning: Analysing Convolutional and Recurrent Neural Networks for Dead or Live Classification

García-Garví, Antonio; Puchalt-Rodríguez, Joan Carles; Layana-Castro, Pablo Emmanuel; Navarro Moya, Francisco; Sánchez Salmerón, Antonio José (MDPI AG, 2021-07)

[EN] The automation of lifespan assays with C. elegans in standard Petri dishes is a challenging problem because there are several problems hindering detection such as occlusions at the plate edges, dirt accumulation, and ...
