Rectangle Detection

Detection of a dominant rectangle by processing a single image in order to obtain prior information for subsequent image processing algorithms including natural feature tracking (Augmented Reality).

  • No assumptions about the region contents
  • Automatic setting of parameters
  • Efficient computation on off-the-shelf mobile devices
  • Estimation of a transformation for undistortion

Notes: This approach was developed at Graz University of Technology for Bundesdruckerei GmbH.
