Hello.
I'm developing a program that allows the user to select feature points from several images, matching them. However, this brings a lot of error in the input since it is hard for the user to precisely select the desired pixel. On the other hand, I assume that the user wants to place the feature in areas of interest (building/window/door corners, among others). Is there anything I can use to "snap" the user selected feature to the "correct" or most interesting point?
Thanks
