摘要: |
骨骼轮廓数据的提取是进行骨骼三维重构及制造骨骼RP原型的基础。研究根据骨骼CT图像的特点和快速成型制造的要求,提出先进行图像滤波,然后二值化,最后提取骨骼轮廓并矢量化的方法,并对其中各环节的数据处理算法进行了理论分析和试验研究,得出中值滤波是适应于骨骼图像去噪的方法,最大类间方差法是进行骨骼图像二值化分割处理的最适合方法。 |

Research on RP-oriented bone CT image processing |

Abstract: |
The extraction of bone’s contours is the base of bone’s 3D-reconstruction and RP prototype.According to the features of bone’s CT images and the demand of RP,the paper gives a method in which the filtration,binarization,bone’s contour extraction and vectorization is done orderly.Theoretical analysis and experimental study have been done for each step.In bone’s CT image processing,the media-filter method is feasible,and the Ostu’s method with maximum variance between two classes is more suitable for binary image processing. |
