  • To put forward an improved Geometricactive contour (GAC) model based on the edge flow forsegmentation of concrete Computed tomography (CT) images.An edge flow vector field is constructed at each pixellocation basing on the integration of image intensity, color,and texture characteristics to make the vector field point tothe direction of potential boundary pixels. The GAC fieldobtained by the diffusion of the edge flow vector is regardedas the external potential force of the GAC model. Then thecurve propagation is guided by the improved GAC model.The experimental results obtained by applying the methodto segment concrete CT images. By the integration of theedge flow into the GAC model, the segmentation qualityis obviously improved.
