First Claim
Patent Images
1. A method comprising:
- generating an image pyramid of an image frame;
detecting a plurality of interest points within the image pyramid; and
extracting, via a processor, feature descriptors for each respective interest point, wherein extracting the feature descriptors includes extracting the feature descriptors that are rotation invariant and generated without determining orientations.

Abstract
Various methods for tracking and recognition with rotation invariant feature descriptors are provided. One example method includes generating an image pyramid of an image frame, detecting a plurality of interest points within the image pyramid, and extracting feature descriptors for each respective interest point. According to some example embodiments, the feature descriptors are rotation invariant. Further, the example method may also include tracking movement by matching the feature descriptors to feature descriptors of a previous frame and performing recognition of an object within the image frame based on the feature descriptors. Related example methods and example apparatuses are also provided.
