Image Processing
The image processing unit obtains 2D coordinates of all of the markers in each frame. It gets Deinterlaced frames as input and produces an Excel file of 2D coordinates of markers in an appropriate coordinate system defined by the user
Markers are made of Special phosphoric materials that distinguish them from background
