beeTrack1 is a c++ program using openCV libraries. Here is an example of it processing video:

Processing steps for each frame:

1. Convert image to grey scale.
2. Threshold based on grey value.
3. Filter to smooth the noise.
4. Draw a contour around each object.
5. Calculate area of each object and color code it based on size
6. Check each track to see if it falls within a contour of an object.
7. If so, append the center coordinates of the object to the track. If not, start a new track.
8. When the track ends, increment the In or out counter depending on where the track ends.
