Abstract:
Blood fow refects the eye’s health and is disrupted in many diseases. Many pathological processes
take place at the cellular level like as microcirculation of blood in vessels, and the processing of
medical images is a difcult recognition task. Existing techniques for measuring blood fow are limited
due to the complex assumptions, equipment and calculations requirements. In this paper, we propose
a method for determining the blood fow characteristics in eye conjunctiva vessels, such as linear and
volumetric blood speed and topological characteristics of the vascular net. The method preprocesses
the video to improve the conditions of analysis and then builds an integral optical fow for defnition
of fow dynamical characteristic of eye vessels. These characteristics make it possible to determine
changes in blood fow in eye vessels. We show the efciency of our method in natural eye vessel
scenes. The research provides valuable insights to novices with limited experience in the diagnosis and
can serve as a valuable tool for experienced medical professionals.
