Robust local feature detector and descriptor

Goal: Robust matching of features between multiple images using a Hessian-based detector and a suitable descriptor. A detector and descriptor that takes into account the approximately known distortions will have a much higher matching rate, especially when fisheye or wide angle images are used.

  • Implementation of the feature detector and descriptor, and a suitable test suite to verify the correctness of the implementation.


A desired result of the projects would be:

  • C or C++ library that implements the detection and description steps.
  • An executable for extracting features from image file.
  • Test suite to evaluate descriptor on a large amount of images.
  • Integration of the library into hugin

Project Schedule

  • 0w April 9 - Application selection
  • Interim Period: Learn more about the project, the literature that is being used to develop it, and build a testing set with ground truth ~200 images. This can be done asking for pictures to the mailing list.
  • 0w May 28 - Begin coding for the project
  • 1w June 4 - Create all the evaluation software, (mainly available from the website of Krystian Mikolajczyk)
  • 3w June 18 - Implement of the algorithm chosen for the detector of feature points on the image.
  • July 9: Students upload code to code.google.com/hosting; mentors begin mid-term evaluations
  • 7w July 23 - Implementation of the descriptor to match the feature points detected.
  • 10w August 13 - Benchmark and code optimization.
  • 11w August 20 - Final report (Google Deadline for all student work),students upload code to code.google.com/hosting; mentors begin final evaluations; students begin final program evaluations.
