GDV DIAGRAM

SETTINGS
Enter the program. The preliminary menu, representing the parameters of the GDV-grams processing will open (fig.1)

Fig.1. "GDV Diagram" dialogue window.

To set up the level use Remove all fragments up to_ pixels.

The recommended level of "noise" when working with GDV-grams - 30-80 pixels. That means, all the elements, which do not correspond to the given size will be removed during processing.

Level Background
Use buttons of Level background menu. The background of white-and-black images ranges from 0 - absolutely black to 255 - absolutely white. The decrease of background starts from "absolutely white". This can be applied to mark the contrast parts of GDV-grams or to remove the excessive "noise". The recommended Level background for the patient examination - 230-250.

Colorization of GDV-grams
Grey palette and Default palette -b/w images
Intensity palette - every colour has an equal area in the spectral curve;GDV-grams are intensively colored.
Equal palette,- spectral length is divided to the equal parts, to every part is attributed its own color; GDV-grams are less intensively colored

Normalize palette - the regime is under development.

Setting up of the DIAGRAM regime.
If Automatic regime is chosen, the DIAGRAM is built automatically. This regime is recommended for the demonstrations only.

BUTTONS
About - information on the current version of the GDV AURA.
Quit - quit working with the program
Next - proceed working
Calibration - procedure, necessary in the beginning of operation with GDV Camera and for metrology testing (usually twice a year)
