3D human pose estimation from a single image via distance matrix regression
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Text en actes de congrés
Accés obertThis paper addresses the problem of 3D human pose estimation from a single image. We follow a standard two-step pipeline by first detecting the 2D position of the N body joints, and then using these observations to infer ... -
3D human shape and pose from a single low-resolution image with self-supervised learning
(2020)
Text en actes de congrés
Accés obert3D human shape and pose estimation from monocular images has been an active area of research in computer vision, having a substantial impact on the development of new applications, from activity recognition to creating ... -
3D mapping for urban service robots
(IEEE Press. Institute of Electrical and Electronics Engineers, 2009-10-11)
Text en actes de congrés
Accés obertWe present an approach to the problem of 3D map building in urban settings for service robots, using threedimensional laser range scans as the main data input. Our system is based on the probabilistic alignment of 3D point ... -
3D modelling of leaves from color and ToF data for robotized plant measuring
(2011)
Text en actes de congrés
Accés restringit per política de l'editorialSupervision of long-lasting extensive botanic experiments is a promising robotic application that some recent technological advances have made feasible. Plant modelling for this application has strong demands, particularly ... -
3d semantic representation of actions from effcient stereo-image-sequence segmentation on GPUs
(2010)
Text en actes de congrés
Accés obertA novel real-time framework for model-free stereo-video segmentation and stereo-segment tracking is presented, combining real-time optical flow and stereo with image segmentation running separately on two GPUs. The ... -
3D sensor planning framework for leaf probing
(Institute of Electrical and Electronics Engineers (IEEE), 2015)
Text en actes de congrés
Accés obertModern plant phenotyping requires active sensing technologies and particular exploration strategies. This article proposes a new method for actively exploring a 3D region of space with the aim of localizing special areas ... -
3D vehicle detection on an FPGA from LiDAR point clouds
(Association for Computing Machinery (ACM), 2019)
Text en actes de congrés
Accés obertIn this paper is presented a deep neural network architecture designed to run on a field-programmable gate array (FPGA) for detection vehicle on LIDAR point clouds. This works present a network based on VoxelNet adapted ... -
3DPeople: modeling the geometry of dressed humans
(2019)
Text en actes de congrés
Accés obertRecent advances in 3D human shape estimation build upon parametric representations that model very well the shape of the naked body, but are not appropriate to represent the clothing geometry. In this paper, we present an ... -
A comparison between model-based and data-driven leak localization methods
(2023)
Text en actes de congrés
Accés obertWater networks are crucial infrastructures for the sustainability of modern cities, and hence their proper operation is of great importance. This includes the fast detection, localization and repair of leaks, which may ... -
A comparison between two representatives of a set of graphs: median vs barycenter graph
(Springer Verlag, 2010)
Text en actes de congrés
Accés obertIn this paper we consider two existing methods to generate a representative of a given set of graphs, that satisfy the following two conditions. On the one hand, that they are applicable to graphs with any kind of labels ... -
A comparison of three methods for measure of time to contact
(IEEE Press. Institute of Electrical and Electronics Engineers, 2009-10-11)
Comunicació de congrés
Accés obertTime to Contact (TTC) is a biologically inspired method for obstacle detection and reactive control of motion that does not require scene reconstruction or 3D depth estimation. Estimating TTC is difficult because it requires ... -
A competitive strategy for function approximation in Q-learning
(2011)
Text en actes de congrés
Accés obertIn this work we propose an approach for generalization in continuous domain Reinforcement Learning that, instead of using a single function approximator, tries many different function approximators in parallel, each one ... -
