The color operator helps to track regions of particular colors. Colors are chosen by clicking on pixels in the operator's image window. When am pixel is clicked on, a color is put into a list of colors. Each color is compared against pixels in the incomming image. Only pixels matching colors in the list are copied to the resulting image. A threshold value determines the window around each color by which compared colors can vary and still match. For instance, if color 30,10,250 is chosen, and the window is 10, pixels falling in the range of 30±10, 10±10, 250±10 are copied to the resulting image. Window thresholds for each plane can be individually set using messages.

Inlets & Arguments:

#	Name	Arg	Description

2	window	l,lo	Fuzzyness in matching colors in a list. Represents a window around pixel color intensity values.
3	value	h,hi	Value to assign pixels that don't match colors in a list.

Outlets:

#	Name	Description
1	color segmented image	Image with only pixels of specified colors.

Messages:
