A Curvature Based Method for Blind Mesh Visual Quality Assessment Using a General Regression Neural Network

2016

International audience; No-reference quality assessment is a challenging issue due to the non-existence of any information related to the reference and the unknown distortion type. The main goal is to design a computational method to objectively predict the human perceived quality of a distorted mesh and deal with the practical situation when the reference is not available. In this work, we design a no reference method that relies on the general regression neural network (GRNN). Our network is trained using the mean curvature which is an important perceptual feature representing the visual aspect of a 3D mesh. Relatively to the human subjective scores, the trained network successfully asses…

La calidad percibida de los servicios deportivos: diferencias según instalación, género, edad y tipo de usuario en servicios náuticos. (The perceptio…

2008

En el ambito de la gestion deportiva, la calidad de losservicios deportivos y la satisfaccion de los usuarios es un area de gran desarrollo. Este trabajo pretende determinar el grado de calidad percibida en unos servicios deportivos de caracter publico como son unas escuelas de actividades nauticas. Para ello se analizaron 2375 usuarios de estas escuelas que contestaron un cuestionario sobre calidad de servicio percibida y satisfaccion con el servicio recibido. La escala de calidad percibida utilizada determino diez dimensiones de calidad: las clases, el tiempo libre, el entorno nautico, los horarios, la comida, el material nautico, la comida complementaria, la conserjeria, la limpieza y la…
