Assessment of spatiotemporal heterogeneity of two-dimensional images on the example of photoplethysmograpic imaging of hemodynamics

Background and Objectives: The problem of representation of multidimensional data on a two-dimensional plane arises during the processing of a series of two-dimensional images in the spatiotemporal and time-frequency domains. When implementing time-frequency analysis, each point of the object is cha...
