In view of industrial spot and the particular requirements of the segmentation for the end image when the bar steel were bundled up

a new image segmentation approach is presented. At first. the image is preliminary segmented with threshold method and edge based method

by using the fast 2-D entropic thresholding algorithm and the simple gradient operator respectively. Then the results from the two methods are fused and integrated

the target areas are identified and the adhesions are removed

in which genetic algorithm is implemented. The fusion-based technique is shown to perform very well in terms of robustness to noise and adhesions

and the calculating time is not evidently added. The experimental result shows that the proposed approach is efficient in improving the quality of segmentation and fitting the industrial requirement.
