In this chapter, it is proposed the solutions of a problem of changing image resolution based on the use of computational intelligence means, which are constructed using the new neuro-paradigm—Geometric Transformations Model. The topologies, the training algorithms, and the usage of neural-like structures of Geometric Transformations Model are described. Two methods of solving a problem of reducing and increasing image resolution are considered: using neural-like structures of Geometric Transformations Model and on the basis of the matrix operator of the weight coefficients of synaptic connections. The influences of the parameters of image preprocessing procedure, as well as the parameters of the neural-like structures of Geometric Transformations Model on the work quality of both methods are investigated. A number of the practical experiments using different quality indicators of synthesized images (PSNR, SSIM, UIQ, MSE) are performed. A comparison of the effectiveness of the developed method with the effectiveness of the existing one is implemented.
