Method for image segmentation, method for training image segmentation model

An electronic apparatus, comprising:

• a processor;
• a memory configured to store executable instructions of the processor;
• wherein the processor is configured to perform the following steps:
• acquiring, according to an image to be segmented comprising a background, a mediastinum, an artery and a vein, a first segmentation result of the mediastinum, the artery, the vein and the background in a mediastinum region of the image to be segmented;
• acquiring, according to the image to be segmented, a second segmentation result of a blood vessel and the background in an epitaxial region of the image to be segmented;
• and
• acquiring, according to the first segmentation result and the second segmentation result, a segmentation result of the mediastinum, the artery, the vein and the background of the image to be segmented.

A non-transitory computer readable storage medium having stored thereon executable instructions configured to cause a processor to perform the following steps:

• acquiring, according to an image to be segmented comprising a background, a mediastinum, an artery and a vein, a first segmentation result of the mediastinum, the artery, the vein and the background in a mediastinum region of the image to be segmented;
• acquiring, according to the image to be segmented, a second segmentation result of a blood vessel and the background in an epitaxial region of the image to be segmented;
• and
• acquiring, according to the first segmentation result and the second segmentation result, a segmentation result of the mediastinum, the artery, the vein and the background of the image to be segmented.
