Pig lung pathological change scoring method and system based on image analysis

The invention belongs to the technical field of image analysis, and particularly discloses a pig lung pathological change scoring method and system based on image analysis, and the method comprises the steps: obtaining a to-be-detected chest CT image through obtaining the chest CT scanning image of a pig, carrying out the image filtering and image segmentation processing, carrying out the adjustment and labeling of the to-be-detected chest CT image through a labeling instruction of a user, and carrying out the scoring of the pathological change of the pig lung. The method comprises the steps of obtaining a marked CT image to be detected, calling a marked contrast CT image and the marked CT image to be detected to carry out image region feature comparison, determining a feature difference value and corresponding change parameters between the two images, and finally calculating a change score by utilizing each change parameter, so that a user can evaluate the change degree of chest and lung image features of a
