| Popis: | An analysis was carried out, which showed that the task of creating a system for evaluating biomedical images of pathologies of the vessels of the human eye is relevant and needs to be solved, since the existing methods and systems of evaluation, as well as the existing methods of processing biomedical images do not meet the modern requirements for such systems in terms of accuracy , the reliability of processing biomedical images, which leads to the occurrence of errors in the diagnosis in ophthalmological studies. The results of the comparison of the effectiveness of the Kirsch, Sobel, Roberts, Wallace, SUSAN algorithms for processing biomedical images based on the set of information diagnostic features formed are the most informative for image segmentation, the algorithms based on Kirsch filtering and the nonlinear Sobel filter. A system has been developed for evaluating dynamic changes in biomedical images, which allows to evaluate the state of blood vessels and determine the conjunctival index based on the following indicators: the ratio of the diameters of arterioles and corresponding venules; caliber irregularities; meander windings; microaneurysms; glomeruli; reticular structures of vessels; changes in the number of functioning capillaries; arteriolo-venular anastomoses; hemorrhages; perivascular edema; sludge phenomena; microthrombi |
