Semantic and generic object segmentation for scene analysis using RGB-D Data
(Universitat Politècnica de Catalunya, 2018-07-20)
Tesi
Accés obertIn this thesis, we study RGB-D based segmentation problems from different perspectives in terms of the input data. Apart from the basic photometric and geometric information contained in the RGB-D data, also semantic and ... -
Cellular networks for smart grid communication
(Universitat Politècnica de Catalunya, 2018-07-19)
Tesi
Accés obertThe next-generation electric power system, known as smart grid, relies on a robust and reliable underlying communication infrastructure to improve the efficiency of electricity distribution. Cellular networks, e.g., LTE/LTE-A ... -
Deep learning for i-vector speaker and language recognition
(Universitat Politècnica de Catalunya, 2018-05-29)
Tesi
Accés obertOver the last few years, i-vectors have been the state-of-the-art technique in speaker and language recognition. Recent advances in Deep Learning (DL) technology have improved the quality of i-vectors but the DL techniques ... -
Investigation of continuous-wave range-resolved lidar systems for gas detection and concentration measurement
(Universitat Politècnica de Catalunya, 2011-07-27)
Tesi
Accés obertThe techniques for detection of the atmosphere constituents and their distribution in the space have evolved in the last years driven by needs in the environmental, meteorological and climate science fields and backed by ... -
