Comparison of optical and MR‐based tracking [PDF]
Magnetic Resonance in Medicine, 2014 PurposeThe goal of this study was to compare the accuracy of two real‐time motion tracking systems in the MR environment: MR‐based prospective motion correction (PROMO) and optical moiré phase tracking (MPT).MethodsFive subjects performed eight predefined head rotations of 8° ± 3° while being simultaneously tracked with PROMO and MPT.

Using Optical Flow for Tracking [PDF]
, 2003 We present two observation models based on optical flow information to track objects using particle filter algorithms. Although, in principle, the optical flow information enables us to know the displacement of the objects present in a scene, it cannot be used directly to displace a model since flow estimation techniques lack the necessary precision ...

Optical Flow in Deep Visual Tracking
Proceedings of the AAAI Conference on Artificial Intelligence, 2020 Single-target tracking of generic objects is a difficult task since a trained tracker is given information present only in the first frame of a video. In recent years, increasingly many trackers have been based on deep neural networks that learn generic features relevant for tracking.
