Left and right ear region segmentation method based on temporal bone CT (Computed Tomography) plain-scan image

The invention discloses a left and right ear region segmentation method based on a temporal bone CT (Computed Tomography) plain-scan image, and relates to the technical field of medical image processing. S02, area positioning is carried out; s03, carrying out region preliminary segmentation; s04, carrying out threshold segmentation; s05, removing invalid areas; s06, edge detection is carried out; s07, contour extraction is carried out; s08, area refinement is carried out; s09, feature extraction is carried out; s10, carrying out region verification and correction; the method has the beneficial effects that the edges of the ear of the CT image can be extracted through edge detection, then the edges are connected to form a complete ear contour by using an Active Contour Algorithm dynamic contour algorithm, and finally the complete ear contour is extracted, so that the optimization effect of the extracted ear region is improved through region refinement, and the accuracy of the ear region is improved.
