Pixel Correlation

Digital image correlation method is an important optical technique for surface displacement and strain measurement. An approach based on Particle Swarm Optimization algorithm for sub-pixel correlation search is described in this paper. The new Algorithm does not involve reasonable guess of displacement and deformation gradient and the calculation of second-order derivatives of the digital images. Benefiting from the abilities of global optimum and parallelism searching, and compared with genetic algorithm, the new approach can complete the sub-pixel correlation search with high accuracy and less computational consumption. Computer-simulated images are then used to verify this method. The experimental results show that the new approach is a practicable sub-pixel searching method.

The detailed design implemented according to a grant of the Russian Federal Property Fund is focused on the solution of the cross-disciplinary humanitarian problem connected with the analysis of purposeful and sponta-neous processes of socialization of the child, and specif-ic characteristics of the social and pedagogical activity aimed at harmonization of the relations "the child - so-ciety" in modern unstable public conditions. The frag-ment of a research of processes of spontaneous sociali-zation of the child connected with the estimated dis-course presented in a social situation of its development is reflected in article. In it short characteristic of the post-nonclassical methodology focused on the analysis of chaotic conditions of social reality and essence of the person who acts as the language personality who is not existing "to language" is presented. Possibilities of post-nonclassical methodology in a research of a phenome-non purposeful - spontaneous socialization of the child are characterized. In article the specifics of the social and pedagogical activity aimed at harmonization of the relations "the child - society are disclosed from a posi-tion of post-nonclassical approach", the place of a re-search method in its structure is revealed.
