1. A method for determining a centerline of a blood vessel in an image associated with a subject implemented on at least one machine each of which has at least one processor and at least one storage, the method comprising:
obtaining a centerline model used for identifying a centerline of a blood vessel; and
identifying the centerline of the blood vessel based on the centerline model, wherein
the centerline model includes a centerline average model; and
the centerline model is generated by a process including:
registering a plurality of sample images;
extracting a reference centerline of a reference blood vessel in each of the plurality of registered sample images; and
determining the centerline average model based on a plurality of reference centerlines of the reference blood vessel in the plurality of registered sample images.
