SOBEL AND PREWITT EDGE DECTECTION USING LabVIEW

[Jalashwa]

Hi everyone,

i am doing a pattern matching project for which i may have to use Sobel Edge Detection and the Prewitt Edge Detection. 

i was digging in the discussion forum but did not find much.

i shall appreciate if someone can help me with some resources on the above mentioned topics so that i can carry out the operation using LabVIEW.

Regards

Hi,

The IMAQ Edge Detection VI gives you a choice of which method you would like to use:

Hey phil 

 thank you for the info .. i never thought it would be there in the IMAQ Find Edge. you have helped me save a lot of time.

i have also made a vi using the same function ... unfortunately it is not working .  i have trouble understanding the Context help  as  well.

i would be delighted if you could help me run the vi

Thanks again
