A new velocimetry based on dynamic image processing is proposed. On the analogy of laser Doppler velocimetry, a dynamic scene is transformed to a sequential scene with sinusoidal field of gray-value. From temporal change of accumulated gray-value of each frame, we can evaluate a velocity information of moving particles using spectral analysis. The validity and usefulness of the velocimetry is confirmed using artificial images created by computer simulation.
