Computer Vision Lab Computer Vision Lab Optical flow estimation is a crucial task in computer vision that provides low level motion information. despite recent advances, real world applications still present significant challenges. this survey provides an overview of optical flow techniques and their application. Optical flow is the pattern of apparent motion of image objects between two consecutive frames caused by the movement of object or camera. it is 2d vector field where each vector is a displacement vector showing the movement of points from first frame to second. Figure 4(d) shows the optical flow obtained with the subspace model and a robust estimator. the model was found to greatly increase the quality of the optical flow estimates, and the temporal variation in the subspace coefficients were then used to recognize linguistic events.

We demonstrated a system which uses vision processing techniques to improve the estimation of the state of a jackal ugv from clearpath robotics. we applied feature tracking, optical flow, and perspective transform to derive the estimated motion of the robot from a camera alone. Post lab exercise: a source image will be transformed into the desired perspective view by computing the homography using dlt that maps the source points into the desired points. Optical flow idea first introduced by psychologist jj gibson in ~1940s to describe how to perceive opportunities for motion. This tutorial will show you how to obtain the transformation matrix from 2 sets of 4 points from the image, where the first set of points indicates the source while the second set for the target.
