Different methods of improvement and recognition of images

Different methods of improvement and recognition of images are considered. The description of algorithms of selection, segmentation, description and identification of objects is submitted. The special attention is given to the methods of the description of objects: chain codes, Fourier transform, signature; to the methods of improvement of the image on spatial and frequency domains.

Algorithms, which are used for recognition of simple geometrical figures and numbers are realized and described. Here have come: a method of comparison of the areas of figures, a method with use of Fourier transform, a method of crossings of object straight lines.
