The Development of Distance Estimation in Optic Flow

Perception, 2004
In three experiments we tested the ability of children aged 8 to 12 years and adults to locate a target in an optic texture flow projected onto the ground. During the exposure phase, a static target (diode) was lit up at 6 m or 8 m on the ground in front of the subject. During the pointing phase, the subject was asked to indicate the perceived location

Optical Flow Based Pose Estimation

Proceedings of the 2018 2nd International Conference on Cloud and Big Data Computing, 2018
In this paper, we present a new variant of ICP (iterative closest point) algorithm based on optical flow for finding better 3D point correspondence and computing six-degrees of freedom (6-DOF) pose of the rigid objects. Our approach integrates optical flow algorithm to ICP method, and proposed method gets advantage of higher resolution of the RGB ...

Optical flow estimation: Advances and comparisons

1994
This contribution investigates local differential techniques for estimating optical flow and its derivatives based on the brightness change constraint. By using the tensor calculus representation we build the Taylor expansion of the gray-value derivatives as well as of the optical flow in a spatiotemporal neighborhood.

Estimation of optical flow for occlusion using extrapolation

Proceedings 2000 International Conference on Image Processing (Cat. No.00CH37101), 2002
The accuracy of optical flow estimation is much worth on the occluded and appeared objects. In this paper, we describe an extrapolation method for improving the accuracy of optical flow estimation based on the characteristics of constraint lines in the velocity space and the extraction of the occluded/appeared regions using cluster analysis.

Multiple Combined Constraints for Optical Flow Estimation

2007
Several approaches to optical flow estimation use differential methods to model changes in image brightness over time. In computer vision it is often desirable to over constrain the problem to more precisely determine the solution and enforce robustness.

Optical Flow Estimation Using Genetic Algorithms

2006
This paper illustrates a new optical flow estimation technique, which builds upon a genetic algorithm (GA). First, the current frame is segmented into generic shape regions, using only brightness information. For each region a two-parameter motion model is estimated using a GA.
