Local algorithm for segmented image interpolation.

LI Jiang\|yun, YANG Xun\|nian, WANG Guo\|zhao (Institute of Computer Graphics and Image Processing, Zhejiang University, Hangzhou 310027, China)  
Usually in medical serial slices, the size of a pixel within a slice is much less than the spacing between the planes defined by the slices. But in image processing, they are often asked to have the same resolution in all three dimensions. Besides this, the interpolated images among segmented serial images should also be segmented. A novel local algorithm was used for the interpolation of serial segmented images. The method generated all segment and color information for each new interpolating point that is only dependent on its local blocks of pixels in its near slices. The shapes of the objects on the interpolated slices and their original adjacent slices changed progressively and naturally, and the algorithm was implemented reliably, experiments on medical serial slice image interpolation showed that the new algorithm can generate clear and accurate new pictures. This method was successively applied in a 3\|D Medical Image Visualization and Reconstruction System.
