Segmentation of Industrial Computerized Tomography Image Based on Two-Dimensional Histogram Method

The high resolution industrial CT image is useful for its three-dimensional information of the object.In the testing of the defect of workpiece,the testing efficiency by using image segmentation method to recognize and reveal the defect is enhanced.The bit-window method in the pre-process of the CT image and two-dimensional histogram method in the image segmentation were successively adopted and the defect of a inspected workpiece was revealed very well.Further more,these methods can solve similar problems.
