Patch-Duplets for Object Recognition and Pose Estimation
2003 (English)Report (Other academic)
This report describes a view-based method for object recognition and estimation of object pose in still images. The method is based on feature vector matching and clustering. A set of interest points, in this case star-patterns, is detected and combined into pairs. A pair of patches, centered around each point in the pair, is extracted from a local orientation image. The patch orientation and size depends on the relative positions of the points, which make them invariant to translation, rotation, and scale. Each pair of patches constitutes a feature vector. The method is demonstrated on a number of real images.
