Computer Image Processing of X-ray Bronchus Image Dong Gang

The computer image processing techniqte tsed in X-ray brenchts image s presentedin this paper. Noise has been smoothed by tse of a variable weighted wincow methcd.The boughs and twigs of bronches have been enhanced with a piecewise linear stretch andlog transform. A multicorner edge detecting operator has been intrcctced to get the edgeimage of bronchts and make it more clearly.
