Particle Analysis Sub-Pixel Resolution?

[simply_me]

Hello,

I've tried to find literature about the resolution of NI's Particle Analysis.

I read it goes up to 1/10 of the original resolution as far as rectangle boundaries, but does is apply to all of the parameters as well?

Thank you,

Hello Simply Me,

Could you clarify a bit more on what you mean by the sub-pixel resolution? Could you also point me to the document that said it would go up to 1/10 of the original resolution for rectangle boundary?

Hi Andy,

I've found a number of resources that state that particle analysis have a sub-pixel accuracy:

http://www.ni.com/vision/software.htm

and :

This one says that it has up to 1/10 of a pixel, but I'm not sure it's NI's

(under NI Vision Development Module):

It's important for me to know if the vi I've attached have a sub-pixel accuracy or not (and if it has, what is it).

Thank you,

Hello simple_me,

The subpixel accuracy is actually about 1/25 of a pixel. You can find a detailed information in the NI Vision Concepts Help by navigating to Start > Programs > National Instruments > Vision > Documentation > NI Vision > NIVisionConcepts

Thank you Andy, I wasn't aware of the documentation files.
