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…
An ordinal CNN approach for the assessment of neurological damage in Parkinson's disease patients
Javier Barbero-Gómez, Pedro-Antonio Gutiérrez, Víctor-Manuel Vargas +2
3D image scans are an assessment tool for neurological damage in Parkinson's disease (PD) patients. This diagnosis process can be automatized to help medical staff through Decision…
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…
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…
