Optical Flow Test

Test Opencv Optical Flow

• Detect and track corner features using LK optical flow.
• Keep tracking about 80 points.
• TODO : filter tracked points using two view geometry.

Marker Tracker Test

Test Opencv Marker Tracking and demo video

• Have implemented a marker detector. (While, it is not very satisfing, user should focus the marker image in the center to better process the algortihm.)
• Using NCC as the main threshold for refining matches points, and use LK optical flow for getting a rather good initial guess.
• Estimate the homography between the marker image and the input image.
