Abstract

The present application provides an image segmentation system, method and apparatus, and a computer readable storage medium. The method comprises: obtaining image data, wherein the image data comprises at least one rib; determining a rib region, wherein the rib region comprises at least a portion of ribs; randomly selecting a rib in the ribs as a target rib; processing the target rib by using a classifier trained through a machine learning method, and obtaining a rib probability map; determining a starting point of the target rib; carrying out model tracking on the target rib based on the ribprobability map and the starting point; and based on a model tracking result, segmenting the target rib to obtain segmented ribs. According to the technical scheme of the present application, model tracking is carried out based on the machine learning method, so that the robustness of the model tracking algorithm is improved and that the ribs can be successfully segmented in the image is ensured.

Description

technical field [0001] The present disclosure relates to the field of image processing, in particular, to a rib segmentation system and method. Background technique [0002] Medical images are widely used today. In medical images, rib segmentation can provide a basis for analyzing rib anatomy and diagnosing various diseases. Manual segmentation is time consuming. Although the existing automatic segmentation technology can achieve relatively rapid segmentation in most cases, there may be difficulties in some cases, such as unclear borders of ribs due to pathological conditions, ribs adhered to other bones, missing ribs or part of ribs missing, these may cause errors in the rib segmentation results. Therefore, it is desirable to have a rib segmentation method and system with a high success rate to solve the above problems. Contents of the invention [0003] The first aspect of the present application relates to an image processing method. The image processing method may...
