Rotated Object and Angle Detection based on Signature Information

This paper presents a new signature and Fourier descriptor based algorithm for recognizing a rotated object and its rotation angle. Fourier descriptor is used to represent an object using its frequence parameters which are not influenced by rotation. once the object is recognized, the point with the largest auto-correlation coefficient which can be calculated from signature of the object is used to find angle of the object. The outstanding performance of the proposed algorithm has been tested with the test images where more than 10 2D objects arbitrarily located on a table.
