Patent Images
1. A method comprising:
- accessing information pertaining to a two-dimensional image indicative of a three-dimensional object;
detecting homography between said two-dimensional image indicative of said three-dimensional object and a reference object image; and
determining whether said homography indicates pose suitable for image augmentation based, at least in part, on characteristics of an elliptically-shaped area that encompasses at least some of a plurality of inliers distributed within said two-dimensional image.

Abstract
Components, methods, and apparatuses are provided that may be used to access information pertaining to a two-dimensional image of a three-dimensional object, to detect homography between said image of said three-dimensional object captured in said two-dimensional image indicative of said three-dimensional object and a reference object image and to determine whether said homography indicates pose suitable for image augmentation based, at least in part, on characteristics of an elliptically-shaped area that encompasses at least some of a plurality of inliers distributed in said two-dimensional image.

16. An article comprising:
-
a non-transitory storage medium comprising machine-readable instructions stored thereon which are executable by a processor of a mobile device to; access captured image data, the captured image data being representative of a two-dimensional image of a three-dimensional object; detect homography between said two-dimensional image of said three-dimensional object and a reference object image; and determine whether said homography indicates pose suitable for image augmentation based, at least in part, on characteristics of an elliptically-shaped area that encompasses at least some of a plurality of inliers distributed in said two-dimensional image. - View Dependent Claims (17, 18, 19, 20, 21)
