extract contour binary image

[giansorr]

Hi, I've been trying to use the IMAQ Extract Contour VI to get a contour of a seeded jet (is a binary image). t is sent to the IMAQ Extract Contour VI, but this last one fails to find the contour. I don't know if the algorithm is able for this kind of problem.

Could someone help me please? The Vi and the image are attached below.

Hi Giansorr,

thank you for your post on NI forum. In order to perform a Contour Analysis, you can try to analyze some examples you can find at the following path:

<LabVIEW>\examples\Vision\2. Functions\Contour Analysis

The contour algorithm works fine if the image you are going to analyze has wel defined contours.

You can try to run the above examples with your .png image.

Have a nice work.
