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 including determining an edge image of the first and second edge images to have higher resolution than another edge image of the first and second edge images and determining a metric with respect to the edge image with higher resolution; generating an edge mask based on results of the joint edge weighting operation including retaining or eliminating one or more edge pixels of the respective edge image of the first and second edge images as the one or more edge pixels retained or eliminated are determined to be respectively within or outside the metric; 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.
