基于顺序形态学的医学图像插值算法的研究

医学图像插值方法是医学图像三维重建的关键技术，插值的结果直接决定了三维重建的效果.本文在深入研究了顺序形态学理论的基础上，提出了一种基于顺序形态学的插值算法，该算法采用百分位膨胀和腐蚀算子，解决了线性插值和形状插值等算法产生的边界模糊的问题.仿真实验表明该算法产生的断层图像和原有断层图像过渡自然，为后续的医学图像三维重建奠定了基础.

The Interpolation Arithmetic Study of Medical Image Based on the Order Morphology

The interpolation method of medical image is the key technology in domain of 3-d reconstruction of medical image.In this paper,a new interpolation algorithm based on order morphology is presented.The algorithm is implemented using percent dilation and erosion operations to resolve edge illegibility of the other interpolation algorithms like linear interpolation.The order morphological interpolation technique is compared to an existing shape based interpolation method and its advantages include superiority capability on handling various cases such as the branching and holes problem (appearance and disappearance of information) and more accurate volume estimation.By simulation,the arithmetic is proved an effective method,and the produced slice image is similar to original slice image.
