Recognizing Shapes Via Random Chord Samplings

R Hashim & Worthy Martin
A brief introduction to various methods of two dimensional shape recognition is given. A procedure for image-plane rotation and translation invariant object recognition is described. The method is based on sampling random chords from the greylevel image of an object and using the texture information associated with these chords to recognize the object. A voting scheme based on a generalized Hough transform performs the recognition. Schemes for organizing random chord shape descriptions and for matching...
