In the article the metric attributes and attributes, which gain on the basis 
of moment characteristics are considered. The main metric attributes 
(complexity, compact, inertia, symmetric image contours) take account 
of the scale changing and outline extension. Received certain sequence these attributes, 
that typical for the certain image classes.
For the image, the outlines which are already known, the analytical characteristic 
of research and polar moment are performed; the sequences of outlines attributes are extracted. 
The variants of attributes ensemble increasing are proposed 
by the radius-vectors and the digitization step changing.
