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.
