By calculating these image signatures as images are captured, a new current view can be quickly compared to historical views in a manner that is less dependent on the relative orientation of a target and search image. These and other techniques may be employed in a three-dimensional reconstruction process to generate a list of candidate images from among which full three-dimensional registration may be performed to test for an adequate three-dimensional match. In another aspect this approach may be supplemented with a Fourier-based approach that is selectively applied to a subset of the historical images. By alternating between spatial signatures for one set of historical views and spatial frequency signatures for another set of historical views, a pattern matching system may be implemented that more rapidly reattaches to a three-dimensional model in a variety of practical applications."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image signatures for use in motion-based three-dimensional reconstruction","description":"A family of one-dimensional image signatures is obtained to represent each one of a sequence of images in a number of translational and rotational orientations.
