Estimate Homography to do 2D to 3D integration (9): Extract known points in pairs automatically

I. Using bigger color markers

II. Draft code

    - Using "the position of seeds generating from Particle Filter" as hints
    - Do "morphological operation" + "the hints" to segment these color markers more accurately
    - find the central position of points in each marker as known points to EPnP

 
III. Experimental results

     - in Zoom, tilt, viewpoint_change cases, the error of pixels in (x,y) coordinates are 10 to 12 pixels in average
     - The error is higher than using those smaller markers previously (...3 to 5 pixel error in each frame)


IV. Recording a video to simulate the real working case 

     - Has the information of possession point across frames
     - Video:

V. Discussion with supervisor and report the preliminary results

    - 10 pixel error in my case (640x480 in resolution) is acceptable, but still can be improved
    - My 3rd experiment is not limited in scenario, just try to make a real work which can demonstrate our proposed framework works fine... especially with eye-tracker
