Modify/disable Scanline and Feature points

Hello,

we are developing an app wich uses the cloud recognition, we would like to disable the visualized Scanline and the Feature points, I've read in old posts such feature does not exists and it will be implemented, is it still under implementation? I've tried setting alpha to 0 with no success. How these graphics are implemented? I cannot debug it using Unity player, they are not shown in such mode. In Unity are they instanced as game objects? In that case I cannot find them. Are they rendererd directly on the webcam texture?Thank you.
