Fiducial objects: custom design and evaluation
García-Ruíz, Pablo; Romero Ramírez, Francisco J.; Muñoz-Salinas, Rafael; Marín-Jiménez, M.J.; Medina-Carnicer, R. (MDPI, 2023)Camera pose estimation is vital in fields like robotics, medical imaging, and augmented reality. Fiducial markers, specifically ArUco and Apriltag, are preferred for their efficiency. However, their accuracy and viewing ... -
Fisher Motion Descriptor for Multiview Gait Recognition
Castro, F.M.; Muñoz Salinas, Rafael; Guil, N.; Marín-Jiménez, M.J. (2017)The goal of this paper is to identify individuals by analyzing their gait. Instead of using binary silhouettes as input data (as done in many previous works) we propose and evaluate the use of motion descriptors based on ... -
Human interaction categorization by using audio-visual cues
Marín-Jiménez, M.J.; Muñoz-Salinas, Rafael; Yeguas-Bolívar, Enrique; Pérez de la Blanca, N. (Springer Nature, 2013)Human Interaction Recognition (HIR) in uncontrolled TV video material is a very challenging problem because of the huge intra-class variability of the classes (due to large differences in the way actions are performed, ... -
Keypoint descriptor fusion with Dempster-Shafer Theory
Mondéjar Guerra, Víctor Manuel; Muñoz-Salinas, Rafael; Marín-Jiménez, M.J.; Carmona Poyato, Ángel; Medina-Carnicer, R. (2017)Keypoint matching is the task of accurately nding the location of a scene point in two images. Many keypoint descriptors have been proposed in the literature aiming at providing robustness against scale, translation and ... -
Large-Scale Indoor Camera Positioning Using Fiducial Markers
García-Ruíz, Pablo; Romero Ramírez, Francisco J.; Muñoz-Salinas, Rafael; Marín-Jiménez, M.J.; Medina-Carnicer, R. (MDPI, 2024)Estimating the pose of a large set of fixed indoor cameras is a requirement for certain applications in augmented reality, autonomous navigation, video surveillance, and logistics. However, accurately mapping the positions ... -
Mixing body-parts model for 2D human pose estimation in stereo videos
López-Quintero, Manuel I.; Marín-Jiménez, M.J.; Muñoz-Salinas, Rafael; Medina-Carnicer, R. (Institution of Engineering and Technology, 2017)This study targets 2D articulated human pose estimation (i.e. localisation of body limbs) in stereo videos. Although in recent years depth-based devices (e.g. Microsoft Kinect) have gained popularity, as they perform very ... -
Multi-view gait recognition on curved
López-Fernández, D.; Madrid-Cuevas, F.J.; Carmona Poyato, Ángel; Muñoz-Salinas, Rafael; Medina-Carnicer, R. (2017-12-11)Appearance changes due to viewing angle changes cause difficulties for most of the gait recognition methods. In this paper, we propose a new approach for multi-view recognition, which allows to recognize people walking on ... -
Optimal online time-series segmentation
Carmona Poyato, Ángel; Fernández García, Nicolás Luis; Madrid-Cuevas, F.J.; Muñoz-Salinas, Rafael; Romero Ramírez, Francisco J. (Springer, 2024)When time series are processed, the difficulty increases with the size of the series. This fact is aggravated when time series are processed online, since their size increases indefinitely. Therefore, reducing their number ... -
Parallelization Strategies for Markerless Human Motion Capture
Cano, Alberto; Yeguas-Bolívar, Enrique; Medina-Carnicer, R.; Ventura Soto, S.; Muñoz-Salinas, Rafael (2015-10-15)Markerless Motion Capture (MMOCAP) is the problem of determining the pose of a person from images captured by one or several cameras simultaneously without using markers on the subject. Evaluation of the solutions is ... -
Reflection-aware generation and identification of square marker dictionaries
Garrido-Jurado, Sergio; Garrido, J.; Jurado Rodríguez, David; Vázquez, Francisco; Muñoz-Salinas, Rafael (MDPI, 2022)Square markers are a widespread tool to find correspondences for camera localization because of their robustness, accuracy, and detection speed. Their identification is usually based on a binary encoding that accounts for ... -
ReSLAM: Reusable SLAM with heterogeneous cameras
Romero Ramírez, Francisco J.; Muñoz-Salinas, Rafael; Marín-Jiménez, M.J.; Carmona Poyato, Ángel; Medina-Carnicer, R. (Elsevier, 2024)State-of-the-art SLAM methods are designed to work only with the type of camera employed to create the map, and little attention has been paid to the reusability of the maps created. In other words, the maps generated by ... -
