Entrenando una red neuronal Mask R-CNN con imágenes sintéticas para la detección y segmentación de objetos en imágenes reales de maquinaria
(Universidad Católica San PabloPE, 2021)
En los últimos años, las redes neuronales convolucionales se han utilizado ampliamente para resolver problemas como la clasificación de imágenes, la detección de objetos y la segmentación de objetos. Sin embargo, estas ...
Recovering Latent Signals from a Mixture of Measurements Using a Gaussian Process Prior
(IEEE, 2017)
In sensing applications, sensors cannot always mea-sure the latent quantity of interest at the required resolution, some-times they can only acquire a blurred version of it due the sensor’stransfer function. To recover ...
Damage Detection Approach for Bridges under Temperature Effects using Gaussian Process Regression Trained with Hybrid Data
(Asce-amer Soc Civil Engineers, 2022-11-01)
The success of detecting damage robustly relies on the availability of long periods of past data covering multiple weather scenarios and on the information contained in the data used during the learning process. Thus, the ...
A contribution to the estimation of kinematic quantities from linear motion blurred images
(Manizales - Ingeniería y Arquitectura - Doctorado en Ingeniería - AutomáticaDepartamento de Ingeniería Eléctrica y ElectrónicaUniversidad Nacional de Colombia - Sede Manizales, 2020-04)
This thesis introduces a new approach for estimating kinematic quantities, namely the angle the relative speed, and the acceleration from an actual single motion blur image using the Discrete Cosine Transform (DCT). Motion ...
PolishEM: Image enhancement in FIB-SEM
(Oxford University Press, 2020-03)
We have developed a software tool to improve the image quality in focused ion beam-scanning electron microscopy (FIB-SEM) stacks: PolishEM. Based on a Gaussian blur model, it automatically estimates and compensates for the ...
Restauração de imagens em vibro-acustografia
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCC, 2008-03-10)
Vibro-acoustography is an imaging modality that produces a map of the mechanical response of an object to a localized dynamic radiation force produced by an ultrasound field. This technique has been studied and used in ...
Automatic green fruit counting in orange trees using digital images
(2016-09-01)
Yield estimation is an important factor in a production process planning. In the case of citrus crops, can be useful in industrial management and as guidance for farmers, showing a decisive role in the product market ...
