Fuzzy connectedness and object definition: Theory, algorithms, and applications in image segmentation
JK Udupa, S Samarasekera - Graphical models and image processing, 1996 - Elsevier
Images are by nature fuzzy. Approaches to object information extraction from images should
attempt to use this fact and retain fuzziness as realistically as possible. In past image …

An objective comparison of 3-D image interpolation methods
GJ Grevera, JK Udupa - IEEE transactions on medical imaging, 1998 - ieeexplore.ieee.org
To aid in the display, manipulation, and analysis of biomedical image data, they usually
need to be converted to data of isotropic discretization through the process of interpolation. …

New variants of a method of MRI scale standardization
One of the major drawbacks of magnetic resonance imaging (MRI) has been the lack of a
standard and quantifiable interpretation of image intensities. Unlike in other modalities, such …

Shape-based interpolation of multidimensional objects
SP Raya, JK Udupa - IEEE transactions on medical imaging, 1990 - ieeexplore.ieee.org
A shape-based interpolation scheme for multidimensional images is presented. This scheme
consists of first segmenting the given image data into a binary image, converting the binary …
