Computationally effective three dimensional recursive algorithm for calculation of the translation vectors in the optical method for assessment of deformations
An approach to reduce computational costs and simultaneously enhance of noise immunity for construction of the displacement vector fieldis proposed. The approach is based on 3DRS algorithm and incremental technique for the computation of displacements in the image series. The estimates for computational costs at the combined use of the mentioned algorithms under processing of model and experimental images are obtained. Their noise immunity for determination of the displacements were compared with the incremental algorithm used for optical flow calculation. Based on the computational results we offer the recommendations on the computation parameters that provide substantial increase of operation speed and noise immunity for the construction of the displacement vectors.
