Radial Basis Function Neural Network for the Evaluation of Image Color Quality Shown on Liquid Crystal Displays
Vergara Villegas, Osslan Osiris; Cruz Sanchez, Vianey Guadalupe; Ochoa Domínguez, Humberto; Nandayapa, Manuel; Arias del Campo, Felipe; 171515 (2021-02-01)The color quality of an image shown on a liquid crystal display (LCD) can be measured with a spectroradiometer; however, this instrument is expensive, work under controlled illumination conditions with an artificial source ... -
Residual 3D convolutional neural network to enhance sinograms from small-animal positron emission tomography images
Ochoa Domínguez, Humberto; Vergara Villegas, Osslan Osiris; Cruz Sanchez, Vianey Guadalupe; Polanco Gonzalez, Javier; 194726; Rodríguez, Leandro José; Sossa, Juan Humberto (2023-05-05)Positron emission tomography (PET) has been widely used in nuclear medicine to diagnose cancer. PET images suffer from degradation because of the scanner’s physical limitations, the radiotracer’s reduced dose, and the ... -
Study of the Effect of Combining Activation Functions in a Convolutional Neural Network
Vergara Villegas, Osslan Osiris (2020-11-04)Convolutional Neural Networks (CNN’s) have proven to be an effective approach for solving image classification problems. The output, the accuracy and the computational efficiency of a CNN are determined mainly by the ... -
Using Regression Models for Predicting the Product Quality in a Tubing Extrusion Process
Garcia, Vicente (2019-08-01)Quality in a manufacturing process implies that the performance characteristics of the product and the process itself are designed to meet specific objectives. Thus, accurate quality prediction plays a principal role in ... -
Versatile Video Coding
Ochoa Domínguez, Humberto (River Publishers, 2018-12-02)Video is the main driver of bandwidth use, accounting for over 80 per cent of consumer Internet traffic. Video compression is a critical component of many of the available multimedia applications, it is necessary for storage ...
