1. A method for ultrasound image processing, comprising:
obtaining an ultrasound image, wherein the ultrasound image is associated with a blood flow velocity;
determining, based on the ultrasound image, an envelope curve;
determining a plurality of first maximum points of the envelope curve;
obtaining, based on amplitude features of the plurality of first maximum points, a plurality of second maximum points by screening the plurality of first maximum points;
obtaining a plurality of third maximum points by correcting the plurality of second maximum points according to time features of the plurality of second maximum points; and
determining, based on the plurality of third maximum points, one or more parameters relating to the blood flow velocity.
