Abstract
A method for determining a similarity between curves performed by an electronic device includes extracting a candidate curve corresponding to at least a part of a blood vessel and a source curve corresponding to a guidewire from a blood vessel image, sampling the same sampling number of points from each of the candidate curve and the source curve, calculating a similarity level between the candidate curve and the source curve based on the points sampled from the candidate curve and the points sampled from the source curve, and determining whether the candidate curve and the source curve are similar, based on the calculated similarity level.
