DETECTING ASYMMETRIC ABNORMALITIES IN CHEST RADIOGRAPHY BY CONTRALATERAL AND TEMPORAL SUBTRACTION TECHNIQUE USING ELASTIC MATCHING

摘要

A kind of computer disposal chest in method, system and computer-readable medium includes the first image and the second image tea-chest and at least one first image and the second image for having detected rib edge for obtaining digital picture. At least one first image and the second image that the rib edge is detected by relating dot identify an image of approximate rib edge to multiple rib edge model use Houghs, delineate the approximate rib edge identified from practical rib edge and utilize snake model. The system and computer-readable medium of this method further comprise that one of export shift value uses practical rib edge and warpage, and the first and second images generate warp image, which is registered in another first image and the second image, at least part of shift value.
