Overview

 

Selects certain areas of the input image based on how similar they are to a specific color.  The resulting selection takes the form of a map in the red channel of the node's output, with pixels of full brightness indicating areas that completely passed the selection test and black pixels indicating areas that completely failed the test.

 

 

Selector

In this example a Selector node was used to select only the silver parts of

the shield.  The resulting map was then used to color those parts purple.

 

 

 

Inputs

 

The node's only input provides the original image that is to be selected.
