Efficient description of the boundary of the object under observation

Abstract

The efficient description of the object boundaries becomes a challenge when solving problems related to detection or search of certain objects on images as well as recognition or identification of them. The efficiency of the description is achieved by presenting the boundary as a functional series of the coefficients of expansion in the basis of eigenfunctions of the covariance matrix. It is known that the spectral approach is important for the practice of compact description of data. . The results of assessment of the efficiency of encoding the boundary image have been presented. At present, the considered method can be regarded as a practical computational procedure.
