Embodiment Construction

[0024] In the following, the technical term "object" is used in contrast to the background of the image. For medical images, "objects" can represent organs and tissues of interest, such as blood vessels, airways, glands. For optical character recognition, an "object" may represent a character. In some embodiments, medical images are used as examples of images and blood vessels are used as examples of "objects", but the methods, apparatus and systems in the embodiments can be easily and smoothly converted to extract other objects in other types of images. The centerline of the object. Also, the technical term "image" may refer to a complete image or an image block cropped from an image.

[0025] Figure 1(a) and Figure 1(b) respectively show an overview of a method for generating the centerline of an object in an image and a conventional segmentation-based method according to an embodiment of the present disclosure, to perform Compare. The method for generating a centerline ...

Abstract

The invention provides a method and a system for generating a central line of an object, and a computer-readable medium. The method comprises receiving an image comprising the object. The method further includes generating the central line of the object through tracking an image block sequence; generating the central line of the object through tracking the image block sequence comprises tracking acurrent image block according to the position and the action of a previous image block for each image block except for an initial image block; outputting a strategy function and a value function based on the current image block by means of a trained learning network, wherein the learning network comprises a first learning network and a second learning network after an encoder, the learning network is trained through maximally accumulating rewards; and determining the action of the current image block.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to U.S. Provisional Application No. 62 / 824,240, filed March 26, 2019, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates generally to medical image processing and analysis. More specifically, the present disclosure relates to a method and system for generating a centerline of an object (eg, blood vessel, airway, mammary duct, etc.) in an image. Background technique [0004] Various biomedical image applications involve tree-structured complex objects, such as blood vessels and airways. Objects presenting a tree structure are commonly observed in the human body, including human airways, blood vessels (arteries and veins, capillaries), neural structures, and mammary ducts extending from the nipple, etc. Recent technological advances in medical imaging (CT, MRI, fundus camera imaging, etc.) have made i...
