Correlation Analysis of Images by Isotropic Standards

Possibilities of reduction dependence of results processing of image on mismatch dimensional orientation and allocated object are considered in this article. It-s proposed to consider isotropic standards: round and circle. Steepness of correlation function becomes more if differences between sizes of standard figures and objects on image become less. The result of correlation analysis is proposed to process by a filter of high spatial frequencies to the possible application.

Results of processing test image including geometric figures in different size and different spatial orientation are shown. The best results are obtained with application of standard round.

So, using rounds of different diameter, figures of appropriate size on image can be distinguished regardless of their spatial orientation.
