A Fractal Based Region Segmentation Method and Its Application in Casting Defect Recognition
一种在铸件缺陷识别中的区域分形分割方法

In casting defect recognition of an X-Ray image,due to the complex image background,it is difficult to do segmentation with traditional segmentation technology for interested regions,in which the defects are intense. In this paper,fractal feature of the edges is introduced to distinguish which edge belongs to the casting defects in an edge image and the regions containing mass defect edges,e.g. interest regions are segmented by clustering. Directed to the aluminum alloy casting of vehicle wheel X-Ray images,the fractal based region segmentation method of this paper is used for recognition experiments,and the results show that the approach is effective.
