Convergence of Estimates of Image Interframe Deformation Parameters in Pseudogradient Estimation

A local sample of image readings used to find the pseudogradient in estimating the image parameters influences both the convergence of estimates and the computation costs. Problems of estimating parameters of interframe geometrical deformation of images are solved by analysis and selection of values characterizing the speed of convergence of parameter estimates that can be used to optimize the local sample by different criteria.
