WebDec 15, 2016 · There are couple of ways I can think of doing this: 1. Sliding Windowing technique - You can search for the "template" in the global image by making a window, the size of the template, and sliding it in the entire image. You can do this for a pyramid so the scale and translational changes are taken care of. SIFT - Try matching the global image ...
