Image process help - script & image attached!

[marekm]

I've managed to pass fail the jet hole but cannot seem to find a suitable process for the edge failures.
Any advice or examples would be great!

Script and images attached.

Thanks

Marek

Find the vi for centre defect detection.Similarly set a proper threshold and use a particle analysis for edge defect detction

Hope it helps

Labview cannot find IVA Binary Inverse, is this your own VI or part of the IMAQ toolkit?
Did you create this VI using the image assistant or did you do it the old fashion way?

Thanks

I created this from vision assistant.U can call a direct vi from labVIEW. Hope it helps!!!!

have u done with your second part?I will not advice you to go with pattern matching.Apply a laplacian filter with highlight details then set a proper threshold.This i feel will increase your consistency

[marekm]

I am new to image processing. Do you have a script file example I could look at?

Many thanks

Thanks for your help guys, I can now reliably check for swarf in the centre jet.
However, I still have the major problem of checking for the inperfections around the outside edge of the jet. I tried using a laplacian filter to highlight the edges and create a threshold but I haven't had any reliable success (I have to admit I don't know to configure the filter correctly!).
Any ideas on this part?

Thanks again!
