Description of the shape of the image object

Abstract

When performing many tasks of industrial control, detection, search, recognition, medical diagnostics and fast transmission of images by unmanned aerial vehicles, the problems of efficient description of the objects of interest occur. The spatial data may have high dimensionality. The paper discusses the methods of compact presentation of the object contour on the basis of successive application of the spatial or spectral encoding of two dimensional signals. The comparative assessment of the efficiency of compression of the method under consideration and that of the entropy encoding method is presented.
