Datasets

The datasets contain properties of an object. They are added to an object by some modules.

For example, the base properties of a path or a contour are added by the “Track objects” module. The color average property is added by the module “Extract the contours’ images”.

Path

Property	Sub-property	Description	Provided by the module
position
	x	X coordinate
	y	Y coordinate
velocity
	x	X velocity component
	y	Y velocity component
	absolute	sqrt(X*X+Y*Y)
acceleration
	x	X velocity component
	y	Y velocity component
	absolute	sqrt(X*X+Y*Y)
color average			Extract the contours’ images
	red	Average red color on a circle around each position of the path.
	gree	Average green color on a circle around each position of the path.
	blue	Average blue color on a circle around each position of the path.
motion		Number of pixels changed on a circle around each position of the path.	Motion
