Embodiment Construction
[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0033] Please refer to figure 1 , the present invention provides a tracheal tree hierarchical extraction method combining multi-information fusion network and region growth, which comprises the following steps:
[0034] Step S1: Acquire a CT image of the lungs, first use a Gaussian filter to smooth the CT image, and then use a Frangi filter to enhance the trachea. Finally, the image is normalized, and the contour of the lung and the ROI (Region of interest) of the lung are extracted;
[0035] Step S2: Based on the automatic classification and labeling algorithm, classify the trained trachea label data, obtain the label information of the trachea, main bronchi, lobar bronchus and pulmonary segmental bronchus, and divide the two tracheal branches of the overall trachea subset and the small trachea subset Sets are used to train two networks separately; ...
