Kinect depth image

Hi guys.
I am trying to extract the specific range of color that one texture. My image is the kinect depth openni.

Exists anything node to extract the especific color of texture in the same position on the texture.

My Idea is extract the use the color to extrac the especific point of diferents high, and use contur to obtain the position.


Pipet node?

the simplest way is keying shader
but contour is way slow, i’d rather use compute shader

colorramp filter ?

if you have just one user: ColorRamp FX, or Posterize FX > tracker(EX9.Texture.Anylysis)> so you get XY pos
