Laser speckle contrast imaging (LSCI) is a
powerful tool for blood flow mapping. In this paper, we
described a simple algorithm based on histogram analysis
of laser speckle contrast image to provide rapid differ-
entiation between macro- and microcirculations. The
algorithm was successfully verified by the study of blood
flow in rat cortex under functional activation.
