The paper discusses the features of applying the method of local compensation of video frame displacements in the study of microcirculation parameters by the methods of video capillaroscopy (VCS) and microphotoplethysmography (micro-PPG). The results of the assessment and compensation of local displacements of images of the capillary network in the region of the hand of a conditionally healthy volunteer are presented. The result of the computation of the synthesized image of capillaries with equalized contrast based on the processing of a locally-combined sequence of video frames is shown. An example of capillary visualization using the frequency analysis of locally aligned video frames is given. The effectiveness of the method of local image stabilization within the study of the capillary network of mucous membranes using a laparoscope is demonstrated.
