The article describes in detail the effect named “united voting”. This effect allows making the right choice when the correct solutions comprise a very small part of the solution set. This choice is possible if the erroneous solutions are randomly distributed evenly across the solution set. In the proposed method the obtained solutions are reflected in the histogram, and it is necessary to organize its accumulation and analysis in such a way that a remarkable extremum is formed in the position of the correct solution. A formal description of the situations in which this effect can be utilized is given. For two real functions in Euclidean space, it is necessary to find such parameters of the affine transformation of one of the functions that will make it similar to the second function at least locally. A formal description of both the problem and the proposed solution method allows for the application of this approach in a variety of situations. The main technological features that need to be taken into account in order to find the right solution and evaluate its reliability are considered. As an example of the implementation of the proposed approach, a program is described, which searches shift between images of the Earth’s surface taken at a different time. The results of its testing are presented. Possible ways of further generalization of this method of data analysis are noted.
