Shape-based interpolation of CT image with window technology

In this paper,we propose an shape-based interpolation algorithm using window technology. The aim of this algorithm is to reconstruct the three-dimensional object from a group of two-dimensional sets representing sections of that object. Firstly, the window technology and image fusion method are used to get more details what we are interested in of consecutive sets,and then the contour of the image is obtained by using a mathematical morphology morphing approach,for locating the pixels which are corresponding with the interpolation pixels,we employ the relationship between the pixel and the centre of image. Finally,the grey-level of interpolation pixels are the grey-level of the nearest corresponding pixels. Traveling all pixels of the interpolation image,the interpolation image is produced.
