1. A method comprising: performing first and second edge detection operations on respective first and second images to obtain respective first and second edge images; applying a joint edge weighting operation using edges from the first and second edge images; generating an edge mask based on results of the edge weighting operation; utilizing the edge mask to obtain a third edge image; and generating a third image based on the third edge image; wherein said performing the first and second edge detection operations, applying the joint edge weighting operation, generating the edge mask, utilizing the edge mask and generating the third image are implemented in at least one processing device comprising a processor coupled to a memory.
