IMAQ AutoBThreshold.vi

[maocañas]

Hi

I'm depelop an aplication that threshold a set of images image. At first time I thought in a manual threshold (imaq threshold), but the aplication requers that the umbral was dinamic ( change whit some parameter of the images). So I use the imaq AutoBThreshold.vi and the method 'clustering', It's work very good. the problem is that the explication of this .vi is not to much clear, I found a little theory at the IMAQ VISION USER MANUAL PAGE 7-3. If you have some theory  of how this .vi works I will be very grateful whit you.

THANKS : MAOCAÑAS

Hi MOCAÑAS,

The best way to go to understand how a VI works is to check the Help File.

In your VI go to Help»Show Context Help. A little pop-up window will show. Move your mouse over you AutoBThreshold.vi and then click on "Detailed Help" in the botton of the context help window.

The detailed help has everything you should know about that VI. You can also check and example listed at the bottom of the help file page (Circle Distance Example.vi).

If you need anything else, let us know.

Thanks for using NI forums.

Thanks Avarg.

I saw this help, but what I'm really interesting is on the mathematical formulation of the methods (specially metric method)

If you can help me, I'm very greatfull.

THANKS

Maocañas.

Hi MOCAÑAS,

I think the Vision Concepts Manual will be more helpul for you then. Chapter 8 has more mathematical information about thresholding. Anyway, the manual has everything you should know about vision theoretical basis.

There's another version of the manual. Just look for "Vision Concepts" in www.ni.com.

Have a nice day!

thanks a lot my friend Arturo Vargas

I found what I looking for.
At this document  I found all the mathematical formulation of automatic-thresold

THANKSSSSSSSSSSSSSS
