The detection of features is a fundamental step in many computer vision applications. Standing at the beginning of a processing pipeline, the accuracy of such an application is often determined by the accuracy of the detected features. Thus, the development and the evaluation of feature detectors is of high interest in the computer vision community.
Our evaluation is focused on affine invariant region detectors, e.g. (Cordes et al. 2010 ) :

The data set includes:

  • Image sequences showing planar scenes with changes in illumination and perspective.
  • Highly-accurate homography matrices H for each image pair. The matrices determine the mapping between the images. In order to provide fair results, the matrices are computed without using any feature detector.

For evaluation of region detectors

NEWS:


  • Projection of scene point P to camera planes:

  • Scene restricted to planar geometry
  • With homogeneous coordinates: H*p=p'


  • The data sets contain
    • image sequences in different resolutions (generated from the RAW data of a Canon EOS 350D camera)
    • homographies for the accurate mapping between image pairs of a sequence [1], [2]
  • Our data sets overcome the problem of limited accuracy of the data provided by Mikolajczyk et al. (cf. [1] for details)
  • Additionally, we provide
  • Easy to use and compare: use Matlab evaluation protocol (repeatability, matching score), with our ppm-images and homography-textfiles; evaluation examples: [4,5,6,7,8,9]
  • If you use the data for evaluation, please cite the corresponding paper(s)
  • Our data set has been included in the HBench challenge [10]
