Estimating Optical Flow by Tracking

چکیده
We present a novel method of velocity eld estimation for the points on moving contours in a 2-D image sequence. The method determines the corresponding point in a next image frame by minimizing the curvature change of a given contour point. As a rst step, snakes are used to locate smooth curves in 2-D imagery. Thereafter, the extracted curves are tracked continuously computing the corresponding point for each contour point.

متن کامل3D Keypoint Tracking Based on Hybrid Flow Computation for Human Motion Analysis
In this paper, we propose a robust method to track 3D keypoints for representing 3D human motions under noisy depth environment. Once keypoints are extracted for tracking, the subsequent locations of the keypoints are found by estimating their 3D motion flows. However, estimating the flows using depth information would be a problem, especially, when some depth values are unavailable or the data...
متن کاملMulti-Resolution Estimation of Optical Flow for Vehicle Tracking
This paper presents a hierarchical multi-resolution estimation of optical flow for a vehicle tracking system which can be used in a practical environment. Aiming at accurate estimation of optical flow, we construct a strong feature tracking system based on the Shi-Tomasi approach. As a feature detector, we use a Scale-Invariant Feature Transform (SIFT) algorithm, which not only firmly focuses o...

متن کاملAn Anchor Patch Based Optimization Framework for Reducing Optical Flow Drift in Long Image Sequences
Tracking through long image sequences is a fundamental research issue in computer vision. This task relies on estimating correspondences between image pairs over time where error accumulation in tracking can result in drift. In this paper, we propose an optimization framework that utilises a novel Anchor Patch algorithm which significantly reduces overall tracking errors given long sequences co...
