The method also includes identifying first scale-invariant features in the first image. The first scale-invariant features are based on a scale-invariant feature transform of the first image. The method includes storing the first scale-invariant features in a grouping. The method includes, for each respective image of the plurality of other images, identifying scale-invariant features based on a scale-invariant feature transform of the respective image; matching the scale-invariant features to the grouping; based on the matching, determining a planar homography of the respective image with respect to the grouping; and adding the scale-invariant features of the respective image to the grouping. The method also includes stitching the first image and the plurality of other images into a composite image based on the planar homographies. A field of view of the specimen in the composite image is greater than a field of view of at least one of the first image or the plurality of other images."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for stitching metallographic and stereoscopic images","description":"A method includes receiving a first image and a plurality of other images of a planar surface of a specimen.
