Object Identification And Orientation Estimation From Contours Based On An Affine Invariant Curvature

摘要: New methods of image matching and calculation the affine transformation relating two images an object in different orientations are developed. These applicable to contours extracted from planar-patch objects. The approach is based on a new definition curvature function (previously developed by authors) which invariant all distortions representable transformations. algorithm implemented tested using camera-acquired actual objects, seen exhibit considerable robustness real-world imaging process, as well deviations planarity
