The existing methods of quantitative assessment of the visual quality of digital images are studied. Among the main shortcomings of the studied methods, the following can be singled out. Most of them require a reference image, do not include all the components that affect visual quality and do not take into consideration the laws of human visual perception. It was decided to develop a method for quantitative assessment of the visual quality of images, which will work without a reference image and will take into account the regularities of human visual perception.

It is presented the main results of general approach to building method of deformation strength calculation of defective span bridge structures in a probabilistic formulation, based on the method of statistical tests.

In this article are presented the basic general approach principles to the development of the technique for deformation resistance calculation of the defective span bridge construction in a probabilistic formulation, based on the method of statistical testing operations.
