摘要

The present invention has disclosed a segmentation algorithm for pulmonary nodule in chest radiograph, which comprises applying ray-casting approach on an image to get cast rays; fitting the intensity profile of each cast ray by using a polynomial curve; smoothing the polynomial curves; and searching two edge pixels in each smoothed curves. With this invention, possible edge of nodules in a chest radiograph can be identified robustly and efficiently.
