Converting RGB to Grayscale

[bauer65]

Hi everyone, I need you advice and help if possible.

The purpose of my aplication is to count and evaluate the amount of euro cents on a picture. I will use radius and surface.

I have a library of pictures of each coin.

On the left, you can see what type of pictures I have to process.

On labview 2009, I use the IMAQ Module to do this operation. I give you my Vi.

The problem is that i can't operate on RGB picture. first I have to convert it to grayscale then binary.

I can't find a way to resolve it.

Do you have any suggestion ? 

Thanks in advance !

Ben

How I convert RGB to Grayscale image without using the IMAQ or vision Development module.

Use color to RGB.  Then google for formulas on how to convert the color components to grayscale.
