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.
