giansorr83 Posted November 26, 2012 Report Posted November 26, 2012 Hello, I am using the Imaq extract contour routine to obtain the points on the contour of an image. I need some informations about this kind of routine that Vision uses to obtain the contours... Somebody knows which is the algorithm that is used? I need some informations? Thanks in advance... Quote
Neville D Posted November 27, 2012 Report Posted November 27, 2012 Older versions of NI Vision had a well written PDF "Vision concepts manual", that explained the algorithms, their pros and cons etc. Newer versions have that removed, and replaced by a painful to read .chm (help) file. It also seems to be broken up into a number of different files. On your PC, under: NI\Vision\Documentation\ NIVisionConcepts.chm, and NIVisionLVBasics.chm. Search through those. You might also do a search on the NI site for some additional presentations by the Vision R&D team that sometimes go in-depth into the algorithms behind some of the functions. I know there was a presentation on the new improved edge-finder routine a few years ago. Neville. Quote
