Abstract:
One of the promising areas of development and implementation of artificial intelligence is the automatic detection and tracking of moving objects in video sequence. In this presentation, we will show analysis of moving objects with application to biomedical images. Stem cells are widely used in regenerative medicine due to their properties of regeneration: differentiation into specialized cells and proliferation through mitosis to produce more stem cells. We developed algorithms by using of integral optical flow and motion maps for identification of main types of cell motions in video-sequences including their directional motion, aggregation and dispersion. We show cell monitoring algorithms that analyze behavior of the cells’ population as a system of dynamical objects by using a concept of the integral optical flow. The presented results are used for monitoring and quantitative analysis of the development of cell cultures, estimating the dynamic changes taking place in them, and determining the population’s heterogeneity and viability. Two more tasks are shown in presentation that use optical flow for dynamic image analysis. A method for determining the characteristics of blood flow in the vessels of eye conjunctiva, such as linear and volumetric blood speed, and topological characteristics of vascular net was developed. We show the efficiency of our method in real eye vessels scenes. Second, a method for monitoring dynamic wound changes in video sequence based on integral optical flow will be shown. Dynamic characteristics of wound tissue changing are introduced and calculated. We show the efficiency of our method in real wound scenes.
