This paper deals with the improvement of optical flow algorithms for strain measurements. The aim of the research is to reduce the computational effort and improve the robustness of the algorithms. The proposed modifications of the algorithms are based on the incremental approach to the estimation of the subsets displacement on the image subsequence, as well as on a three-dimensional recursive search (3DRS). An investigation of the robustness and performance of the algorithms shows the advantage of the proposed modifications.
