Recursive ArUco Markers: A Scalable Fiducial Marker Design for Unmanned Aerial Vehicle Landing Pads
Rafael Munoz-Salinas, Francisco Jose Romero-Ramirez, Sergio Garrido-Jurado
Unmanned Aerial Vehicles (UAVs) increasingly rely on visual fiducial markers for autonomous navigation and precision landing. However, standard markers suffer from limited operatio…
DeepArUco++: Improved detection of square fiducial markers in challenging lighting conditions
Rafael Berral-Soler, Rafael Muñoz-Salinas, Rafael Medina-Carnicer +1
Fiducial markers are a computer vision tool used for object pose estimation and detection. These markers are highly useful in fields such as industry, medicine and logistics. Howev…
3D Reconstruction and Alignment by Consumer RGB-D Sensors and Fiducial Planar Markers for Patient Positioning in Radiation Therapy
Hamid Sarmadi, Rafael Muñoz-Salinas, M. Álvaro Berbís +2
BACKGROUND AND OBJECTIVE: Patient positioning is a crucial step in radiation therapy, for which non-invasive methods have been developed based on surface reconstruction using optic…
Simultaneous Multi-View Camera Pose Estimation and Object Tracking with Square Planar Markers
Hamid Sarmadi, Rafael Muñoz-Salinas, M. A. Berbís +1
Object tracking is a key aspect in many applications such as augmented reality in medicine (e.g. tracking a surgical instrument) or robotics. Squared planar markers have become pop…
Detection of Binary Square Fiducial Markers Using an Event Camera
Hamid Sarmadi, Rafael Muñoz-Salinas, Miguel A. Olivares-Mendez +1
Event cameras are a new type of image sensors that output changes in light intensity (events) instead of absolute intensity values. They have a very high temporal resolution and a…
RealHePoNet: a robust single-stage ConvNet for head pose estimation in the wild
Rafael Berral-Soler, Francisco J. Madrid-Cuevas, Rafael Muñoz-Salinas +1
Human head pose estimation in images has applications in many fields such as human-computer interaction or video surveillance tasks. In this work, we address this problem, defined…
Joint Scene and Object Tracking for Cost-Effective Augmented Reality Assisted Patient Positioning in Radiation Therapy
Hamid Sarmadi, Rafael Muñoz-Salinas, M. Álvaro Berbís +2
BACKGROUND AND OBJECTIVE: The research done in the field of Augmented Reality (AR) for patient positioning in radiation therapy is scarce. We propose an efficient and cost-effectiv…
UcoSLAM: Simultaneous Localization and Mapping by Fusion of KeyPoints and Squared Planar Markers
Rafael Munoz-Salinas, Rafael Medina-Carnicer
This paper proposes a novel approach for Simultaneous Localization and Mapping by fusing natural and artificial landmarks. Most of the SLAM approaches use natural landmarks (such a…
3D human pose estimation from depth maps using a deep combination of poses
Manuel J. Marin-Jimenez, Francisco J. Romero-Ramirez, Rafael Muñoz-Salinas +1
Many real-world applications require the estimation of human body joints for higher-level tasks as, for example, human behaviour understanding. In recent years, depth sensors have…
Mapping and Localization from Planar Markers
Rafael Muñoz-Salinas, Manuel J. Marín-Jimenez, Enrique Yeguas-Bolivar +1
Squared planar markers are a popular tool for fast, accurate and robust camera localization, but its use is frequently limited to a single marker, or at most, to a small set of the…
Fisher Motion Descriptor for Multiview Gait Recognition
F. M. Castro, M. J. Marín-Jiménez, N. Guil +1
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 evaluat…
