1. An image processing system for a catheter procedure, the system comprising:
a memory to at least temporarily store a plurality of candidate routes on which a guidewire is to proceed from a first point as a route is changed by vascular bifurcation points, using a blood vessel image; and
a processor configured to select at least one route corresponding to a current shape of the guidewire based on a comparison of similarities between the current shape of the guidewire and each of the plurality of candidate routes, from an image input during the catheter procedure, wherein
the processor is configured to evaluate and provide a probability of a match between the guidewire and each of the plurality of candidate routes, the probability of the match being generated by calculating and comparing correlation information between the guidewire and each of the plurality of candidate routes.
