1. A clutter filtering method using an ultrasound imaging device, the method comprising:
obtaining ultrasound data from a field-of-view (FOV) of an object;
generating decomposition data including common scale information by performing rank matrix decomposition once on all of the obtained ultrasound data;
estimating local characteristic information by reflecting spatial information on each pixel to the common scale information; and
extracting a blood flow signal by performing filtering on each pixel based on the estimated local characteristic information,
wherein the common scale information is a unique value common to all pixels.
