2D-to-3D facial expression transfer
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Open AccessAutomatically changing the expression and physical features of a face from an input image is a topic that has been traditionally tackled in a 2D domain. In this paper, we bring this problem to 3D and propose a framework ... -
3D CNNs on distance matrices for human action recognition
(2017)
Conference report
Open AccessIn this paper we are interested in recognizing human actions from sequences of 3D skeleton data. For this purpose we combine a 3D Convolutional Neural Network with body representations based on Euclidean Distance Matrices ... -
3D human pose estimation from a single image via distance matrix regression
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Conference report
Open AccessThis 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 pose tracking priors using geodesic mixture models
(2017-04-01)
Article
Open AccessWe present a novel approach for learning a finite mixture model on a Riemannian manifold in which Euclidean metrics are not applicable and one needs to resort to geodesic distances consistent with the manifold geometry. ... -
3D Human pose, shape and texture from low-resolution images and videos
(2022)
Article
Open Access3D human pose and shape estimation from monocular images has been an active research area in computer vision. Existing deep learning methods for this task rely on high-resolution input, which however, is not always available ... -
3D human shape and pose from a single low-resolution image with self-supervised learning
(2020)
Conference report
Open Access3D 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)
Conference report
Open AccessWe 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)
Conference report
Restricted access - publisher's policySupervision 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 object reconstruction from Swissranger sensor data using a spring-mass model
(INSTICC Press. Institute for Systems and Technologies of Information, Control and Communication, 2009)
Part of book or chapter of book
Restricted access - publisher's policyWe register close-range depth images of objects using a Swissranger sensor and apply a spring-mass model for 3D object reconstruction. The Swissranger sensor delivers depth images in real time which have, compared with ... -
3D pose estimation using convolutional neural networks
(Universitat Politècnica de Catalunya, 2015-10)
Master thesis
Open AccessThe present Master Thesis describes a new Pose Estimation method based on Convolutional Neural Networks (CNN). This method divides the three-dimensional space in several regions and, given an input image, returns the ... -

3d semantic representation of actions from effcient stereo-image-sequence segmentation on GPUs
(2010)
Conference report
Open AccessA 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)

3D vehicle detection on an FPGA from LiDAR point clouds
(Association for Computing Machinery (ACM), 2019)
Conference report
Open AccessIn 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)
Conference report
Open AccessRecent 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 3D descriptor to detect task-oriented grasping points in clothing
(2016)
Article
Open AccessManipulating textile objects with a robot is a challenging task, especially because the garment perception is difficult due to the endless configurations it can adopt, coupled with a large variety of colors and designs. ... -
A 3D System for training in endoscopical repair of subcondylar fractures of the mandible
(Springer Verlag, 2008)
Article
Open AccessPoster Session: 12th Annual Conference of Iscas. Conventional treatment of the subcondylar fractures of the mandible is challenging because of the medial and anterior displacement of the condylar fragment and the limited ... -
A bayesian approach to simultaneously recover camera pose and non-rigid shape from monocular images
(2016)
Article
Open AccessIn this paper we bring the tools of the Simultaneous Localization and Map Building (SLAM) problem from a rigid to a deformable domain and use them to simultaneously recover the 3D shape of non-rigid surfaces and the sequence ... -
A branch-and-prune method to solve closure equations in dual quaternions
(2021)
Article
Open AccessUsing dual quaternions, the closure equations of a kinematic loop can be expressed as a system of multiaffine quations. In this paper, this property is leveraged to introduce a branch-and-prune method specially tailored ... -
