Attempt of shaping an united system approach is considered In the article to problems of recognition. Offered algorithm, ensuring recognizing system invariance with respect to external indignations. Discussed possibility and advantage of using a method of recognition basing on information flow compensations. Motivated practicability of deciding a problem of recognition by the method under which problem of recognition takes a type of searching standard requiring minimum expenses on management, than is ensured minimum mutual information, but consequently maximum vicinity of image and standard. Conducted system capacity to work evaluation under external outraging, if its generator of standards can reproduce any one of offered for the recognition of objects.
