A morphological orientation spectra is proposed. This spectrum describes basic directions of shape parts. Fast discrete-continuous algorithm for computing orientation spectrum is presented. It is based on usage of continuous skeleton that is constructed from polygonal shape contour. A definition for disc orientation map is given. Comparison experiments for binary shapes with the usage of orientation spectra are carried out. Cyclic shift and EMD-L1 distance are used for spectra comparison. The obtained results indicate that the aggregation of the thickness spectra with orientation spectra increases the quality of inter-class recognition.
