Estimate Homography to do 2D to 3D integration (14)

I. Studying how to programming 'mouse clicking function' in MATLAB:

   - In Chinese - 1
   - In Chinese - 2

II. Results:

    - A GUI for capturing mouse click event
    - Be able to load a video stream for performing experiment
    - Assuming 30 frames per second. User is capable to locate the 4 fixed points and multiple moving points in a frame extracted from these 30 frames.

        - Here is a demo of the GUI (... because of the monitor resolution can not be recognize by the recording software,  just ignore the incorrect position of the pointer)
