Image filters inside an ROI

Solved!
Go to solution

Hello,

Does anyone know of a way to apply image filters (edge detection, threshold…) to only the portion of an image inside an ROI?

Thanks for any advice,

Brian

Is your ROI a rectangle or some arbitrary shape?

Dear brian,

 I dont know its a good idea or not. Why cant you try image mask (Mask From ROI) function.

Take a look at the attached.  I think this is what you are looking for.  Make sure you have an ROI defined in the 'Original' image control before running.

Randall,

 

This is exactly what I was looking for. I modified your code to use video and it works great!

 

Thank you for your help.
