Motion trajectories
TL;DR: In this paper, a simple algorithm for selecting and linking interesting flow vectors across a sequence of frames for computing motion trajectories is presented, where tokens are tracked that have both interesting pixel gray values in the spatial domain and in the optical flow field in the temporal domain.

Motion detection using the randomised Hough transform: exploiting gradient information and detecting multiple moving objects
TL;DR: The translational-motion experiments with the variant of the technique using gradient information and coping with several moving objects give promising results in two-dimensional-motion detection and estimation, compared with the earlier version of the MDRHT.

Detecting Multiple Moving Objects by the Randomized Hough Transform
TL;DR: The novel approach is tested with both synthetic and real-world sequences of time-varying images and gives promising results in 2D motion detection.

Estimation of Object Motion Parameters from Noisy Images
Ted J. Broida,Rama Chellappa +1 more
TL;DR: An approach is presented for the estimation of object motion parameters based on a sequence of noisy images that may be of use in situations where it is difficult to resolve large numbers of object match points, but relatively long sequences of images are available.

Finding Trajectories of Feature Points in a Monocular Image Sequence
Ishwar K. Sethi,Ramesh Jain +1 more
TL;DR: This work forms the correspondence problem as an optimization problem and proposes an iterative algorithm to find trajectories of points in a monocular image sequence and demonstrates the efficacy of this approach considering synthetic, laboratory, and real scenes.

Detecting moving objects
TL;DR: It is concluded that in realistic situations, detection using visual information alone is quite difficult, particularly when the camera may also beMoving object detection based primarily on optical flow is concluded.
