US Patent 10043280 Method and system for image segmentation

The present disclosure relates to a method and a system for image segmentation, the technique includes: obtaining a lung image and a lung model based on a plurality of chest image samples in a training set; pre-processing a lung image; acquiring a binary image of boundaries of the lung image; performing the generalized Hough transform on the binary image to locate initial boundaries of the lung image and obtain a Hough location; aligning the lung model to Hough location to obtain an alignment result; applying dynamic programming algorithm to the alignment result to obtain a segmentation result; and transforming the segmentation result back to the original coordinate system.
