face authentication in labview

Hello rudra,

Then just using auto-indexing on itself will not be a solution.

A possible solution in this case can be found in the following post:

Hope this helps!

Hello Rudra,

Please take a look at the remarks in this thread:

My original code will not solve your issue, so converting it to 2010 will not solve your issues.

The code illustrated by elset191 in the forum thread above (and all the other posts) should give you the tips and trics on how to solve your issue.

Hello Rudra,

Can you share the code you already have written?

This way we can see where it's going wrong.

Kind Regards,

This is a pretty nice find from the NI Community. Maybe there's something here that could be built upon?

Hello rudra,

Here is a very basic array to image example.

If you adapt it to your needs, then you should be able to use it.

Hello,

I don't really understand why you're talking about the vision assistant.

The selection of which color tracking seems to be done in your application.

To track 4 colours you'll have to use four different hue ranges.
