Special Issue Information

Dear Colleagues,

Computer vision was born and developed with monocular cameras, which laid the foundation for many early advancements in the field. However, the advent of innovative sensors such as depth cameras, event-based cameras, thermal cameras, and LiDAR and the integration of multimedia and multi-camera systems are now addressing the inherent limitations of monocular vision by providing richer and more dynamic data.

This Special Issue welcomes contributions that explore recent advancements with innovative sensors like event cameras or depth sensors, as well as multi-camera systems, pushing the boundaries of what is possible with traditional computer vision.

Submissions to this Special Issue on ‘Beyond monocular computer vision: other sensors, multimedia, and multi-view systems’ are encouraged to provide recent advances by covering a range of topics such as (but not limited to) the following computer vision theory and applications:

  • Depth sensors;
  • Event-cameras and event-based sensors;
  • Multi-camera systems and multi-view geometry;
  • Multimedia systems;
  • Machine learning applied to novel sensors;
  • Light Detection and Ranging (LiDAR);
  • TOF cameras;
  • Thermal cameras;
  • Ultrasound sensors;
  • Multispectral/hyperspectral cameras;
  • Scanning electron microscope (SEM);
  • Omnidirectional cameras.

Magnetic resonance imaging (MRI) is a highly informative diagnostic method; however, its quality heavily depends on the patient’s immobility. Even minimal movements, such as breathing, can cause artifacts that complicate image interpretation, not to mention more significant movements, such as twitching or shivering. Given the high cost of the procedure, repeated scanning is undesirable. The aim of this study was to prepare patients for MRI procedures using specialized training software designed to minimize involuntary movements and improve diagnostic quality. The software tracked participants’ movements in an MRI simulator and reproduced characteristic scanning sounds. The Farnebäck optical flow algorithm detected even the slightest movements captured by the camera, allowing for the evaluation of movements during training sessions and improving patient readiness for actual scanning. A pilot study conducted on a group of 10 students aged 21–27 years demonstrated a significant reduction in the average number of movements during testing—from 27.7 in the first test to 8.3 in the second, corresponding to an average decrease of 19.4 movements. Additionally, two participants showed a noticeable reduction in anxiety levels after the first test, which likely contributed to the decrease in movements, emphasizing the importance of psychological preparation in enhancing training effectiveness. The study results suggest potential improvements in the quality of diagnostic images, which can increase their diagnostic value and enhance patient comfort during actual scanning, reducing the likelihood of repeated procedures.
