A. B. Murynin Journal of Computer and Systems Sciences International , Vol.37 No.4 , 01.1998 , p. 557-560, language: английский ISSN 1064-2307  Аннотация In solving problems of recognition of three-dimensional objects, an information space that includes both informative image features and features of the surface reconstructed by stereo images is applied. The prob- lem of optimization of the dimension of applied information spaces is solved with the use of the criterion of maximum information capacity. In applying an automatic recognizing system, estimates for the optimal number of principal components are obtained.  Ключевые слова computer vision, person recognition, principal components, dimension reduction
