| Research Abstract |
Multidimensional images had become popular in natural science and industrial engineering for observed or measured data. In this research, we have developed a fast approximation algorithm of fea-ture-preserving filters for multidimensional images. Application of the developed algorithm includes noise reduction, frequency decomposition, region segmentation, and feature extraction of the images. Filtering the image consisting of 5133 voxels took only 3 minutes by our algorithm with 3.2 GHz PC where the exact filtering requires approximately 30 years for such huge data.
