Abstract

One of important and interesting problems occurring in visual systems is determining of motion parameters from displacement field. The paper describes algorithms for solving this problem. Examples of effective numerical methods for determining motion parameters can be found in the literaturę starting from early eighties. The methods can be divided into two groups. The first group of the so called nonlinear methods includes algorithms using numerical procedures for calculating zeros of systems of nonlinear eąuation and functlon mlnimization. The second, later group transforras the problem of determining motion parameters into some issues in matrix algebra. The important part of the work is also a software for the described algorithms.
