1. A method for generating a centerline of an object, comprising:
receiving an image containing the object, wherein the image is acquired by an imaging device;
detecting, by a processor, at least one bifurcation of the object using a trained bifurcation learning network based on the image;
detecting, by the processor, end points of the object; and
extracting, by the processor, the centerline of the object based on the end points of the object and a constraint condition that the centerline passes through the detected bifurcation.
