Edge detection based on line profile

asked 2016-05-16 06:38:08 -0600


I'm moving to OpenCV after using imagine processing techniques with the National Instruments Image acquisition and processing routines. There are a series of routines there for sample measurement based on finding edges along a line profile - these allow me to easily measure the dimensions of shapes.

Are there any routines similar to this in openCV? I've found the line iterator, which will give me a profile along a line drawn on an image, but I can't find anything which will take this profile information and determine the edge locations from it.

I don't want 'kernel' type edge finding routines which highlight the location of all edges in an image.

If there aren't routines available and I end up writing my own, is there a mechanism for submitting the new routines for inclusion future releases of openCV?

Do you mean this ?

About submitting the new routines you are welcome

Those are exactly the routines I'm using in LabVIEW. What I'd like are equivalent routines in openCV

I don't think those functions exist in opencv. I think it takes time to write but that's not too hard using opencv and one of your favourite GUI
