Improved multi-scale and structuring element morphological detection in the log CT image

Mathematical morphology is a new subject established based on rigorous mathematical theories. In the basis of set theory, mathematical morphology is used for image processing, analysing and comprehending. It is a powerful tool in the geometric morphological analysis and description. It has become a new theory in the digital image processing field. Moreover, it has deep influence on the image processing theory and technology. Edge is the basic feature in the medical image. It involves a lot of valuable target information of boundary, which is used for image processing, target identifying and image filtering. The mathematical morphology is an effective theory used to locate the image edge. In the paper multi-scale and structuring element in mathematical morphology is used to detect log CT image with defect, and provides a new method in log defect recognition.
