Abstract
An image segmentational recognition method in industrial radiational imaging, comprising the steps of: pre-processing an original image to climate noises; log-transforming, to obtain a linear attenuation coefficient image; edge detecting; edge tracking, to track the points whose edge values are close to each other to obtain edge segments; edge connecting, to connect edge segments; edge connecting, to connect edge segments whose average edge values are close to each other; edge closing; region filling; and region displaying. In comparison with existing arts, the present invention can separate effectively the overlapped objects in an image, raise the efficiency of image inspection, and find out concealed contraband goods more easily.
