Find local maxima in grayscale image using OpenCV

Question

Does anybody know how to find the local maxima in a grayscale IPL_DEPTH_8U image using OpenCV? HarrisCorner mentions something like that but I\'m actually not i

Answer 1

To find more than just the global minimum and maximum try using this function from skimage:

http://scikit-image.org/docs/dev/api/skimage.feature.html#skimage.feature.peak_local_max

You can parameterize the minimum distance between peaks, too. And more. To find minima, use negated values (take care of the array type though, 255-image could do the trick).
