Virtual Marker
Virtual Marker automatically detects color of marker/pen that is placed in front of webcam. As the pen moves, it draws the image on canvas. It is designed in Visual C# 2008 using EmguCV (an openCV wrapper) and AForge.Net Image processing libraries. a. As the user place marker/pen on upper left box of live capture screen, the system captures the image of that portion. b. It then separates all color channels (RGBA) and generates their mean value histogram; these values are then reassigned to from another color which is color of pen. c. CAMSHIFT algorithm is used to track the position on marker. This algorithm is based on Color Tracking technique.
