Find conspicuous points in a 2D image

asked 2018-02-09 11:55:50 -0500

I'm looking for a way to highlight (Track-)points in a webcam image (live).

My attempt to scan the image for unusually bright or dark pixels works in theory, but it can't be applied to real images. So my question is whether it is easy to find conspicuous points with OpenCV and if so, how. (The algorithm should always mark the same points on the paralyzed image.)

Also, I would like to compare the found track points later with track points on other pictures! Maybe one of you guys has an idea!?


Many thanks in advance:)

See just about anything in features2d.

Also everything that starts with corner... in imgProc.
