Virtual Soccer (Real-Time Object Movement Using Optical Flow)
 
01:31
Moving virtual objects around by using optical flow techniques (Horn-Schunk algorithm) to determine velocity vectors. The right graph shows the velocity vector field of one of the soccer balls when the background is moving behind it.

Optical flow
 
09:08
Optical flow or optic flow is the pattern of apparent motion of objects, surfaces, and edges in a visual scene caused by the relative motion between an observer and the scene. The concept of optical flow was introduced by the American psychologist James J. Gibson in the 1940s to describe the visual stimulus provided to animals moving through the world. Gibson stressed the importance of optic flow for affordance perception, the ability to discern possibilities for action within the environment. Followers of Gibson and his ecological approach to psychology have further demonstrated the role of the optical flow stimulus for the perception of movement by the observer in the world; perception of the shape, distance and movement of objects in the world; and the control of locomotion. The term optical flow is also used by roboticists, encompassing related techniques from image processing and control of navigation including motion detection, object segmentation, time-to-contact information, focus of expansion calculations, luminance, motion compensated encoding, and stereo disparity measurement.

Colour identifying and picking robot with OpenCV
 
06:09
This is a colour identifying and picking robot based on HSV colour thresholding using intel's Open CV library. The robot can trace colour that we want to pick with the help of a cam fitted on the robot. The streaming from the cam is processed with C++ code written in OpenCV library and the robot is controlled with parallel port. The complete mechanical assembly is made of low cost materials.
