An original approach to image stabilization in optical coherence tomography and elastography was presented. The key features of the proposed approach are: I) binarization and application of mathematical morphology digital operations; II) parallel construction of a topological skeleton for each optical image with an emphasis on the equivalent high- and low-level signal; III) complexing of topological skeletons; IV) comparison of a sequence of optical images by combined topological skeletons using «quench» points; V) compensation of volumetric motion artifacts by «reassembling» the original sets of interference signals. The computational efficiency of the proposed method with respect to the dynamics of interference signal acquisition by a specific device was achieved by using sequential and parallel operations. Сomputations using the central and graphical processing units, namely GPU and CPU, were combined for this. High efficiency of volumetric motion artifact correction in optical coherence tomography and elastography is ensured by robustness of topological skeletons constructed with emphasis on high-level equivalent signal to speckle noise corresponding to constructive interference (bright speckles). Topological skeletons for low-level equivalent signal are correspondingly robust to dark speckles (destructive interference result).
