imagemagick - remove logo in image or crop image

Question

I have a logo and images which include that logo in corners like top-left, bottom-left, top-right, bottom-right.

Using imagemagick, how can I

(a) remove that logo OR

(b) if not possible, to find the logo it it's x/y coords and crop that image and cut the logo out?

Thanks for any help!

is the logo the same size in all of the pictures? I take it which corner it lands in is random... ? — rm-vanda, Apr 25 '17 at 20:46
no, it's not the same size (logo and main images), and yes, the logo is placed randomly in the corners. — user7261395, Apr 25 '17 at 21:34
Out of interest are these your images you are removing the logo from? — Bonzo, Apr 26 '17 at 07:20

It is unclear from your question whether the logo appears always at the same size in your "watermarked" images.

If the size of the logo is known, you can do a sub-image search and fill or blur over or crop the logo.

If the size of the logo is variable, or unknown, you would need to look for a package (maybe OpenCV) which has Scale Invariant (SIFT) functionality which is not present AFAIK in ImageMagick.

Ok. Thanks a lot. Do you have any idea how to do that using bash/command line? It looks good here but I really want to remove it or crop it. No evidence should be left ;) http://stackoverflow.com/questions/32125281/removing-watermark-out-of-an-image-using-opencv – user7261395 Apr 26 '17 at 19:50
