Microscopic images processing for the wood structure analysis

An algorithm for analysis of wood fibers displacement and changes of the wood structure during deformation is proposed. This algorithm is intended for determination of changes in the structure of plant cells under stress and for study the mechanical properties of fibers. The algorithm is based on determination of the shift between layers by calculation of the optical flows for a sequence of static microscopic images. The use of optical flows allows to identify the particular features of structural deformation within the volume of plant tissues. The algorithm consists of two parts, which makes it possible to accelerate the computational process through parallel computations. The result of the algorithm is the construction of vector fields of the optical flow in three-dimensional space. Using three different types of images allows to determine the deformation, chemical shift and rotation of the fibers. The results of the algorithm allow to evaluate the physiological processes occurring in the deformed tissue of the plant and check the result of mathematical modeling.
