Multiresolution hierarchy co-clustering for semantic segmentation in sequences with small variations
Varas González, David; Alfaro Vendrell, Mónica; Marqués Acosta, Fernando (Institute of Electrical and Electronics Engineers (IEEE), 2015)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper presents a co-clustering technique that, given a collection of images and their hierarchies, clusters nodes from these hierarchies to obtain a coherent multiresolution representation of the image collection. We ... -
Region-based particle filter for video object segmentation
Varas González, David; Marqués Acosta, Fernando (Institute of Electrical and Electronics Engineers (IEEE), 2014)
Text en actes de congrés
Accés restringit per política de l'editorialWe present a video object segmentation approach that extends the particle filter to a region-based image representation. Image partition is considered part of the particle filter measurement, which enriches the available ... -
Region-based particle filter leveraged with a hierarchical co-clustering
Varas González, David (Universitat Politècnica de Catalunya, 2016-11-14)
Tesi
Accés obertIn this thesis, we exploit the hierarchical information associated with images to tackle two fundamental problems of computer vision: video object segmentation and video segmentation. In the first part of the thesis, we ... -

UPC system for the 2015 MediaEval multimodal person discovery in broadcast TV task
India, Miquel; Varas González, David; Vilaplana Besler, Verónica; Morros Rubió, Josep Ramon; Hernando Pericás, Francisco Javier (2015)
Text en actes de congrés
Accés obertThis paper describes a system to identify people in broadcast TV shows in a purely unsupervised manner. The system outputs the identity of people that appear, talk and can be identified by using information appearing in ... -
Visibility estimation of advertising panels in football sequences
Varas González, David (Universitat Politècnica de Catalunya, 2009-09-06)
Projecte/Treball Final de Carrera
Accés obertIn this work, we propose a robust classification system that estimates the advertising panels visibility in real time. For each frame of the sequence, a set of descriptors is extracted to characterize a specific part of ...
