Visualization of medical dataTechnicalUniversityof Lodz

Fast and parallel methods of interpolation of 3D imagesFast algorithms of manipulation of 3D images including rotations, shifts and scalingSegmentation of 3D imagesPrecise mappings of cursors positions into 3D space including real dimensions of visualized objects

The goal of this project was to design and implement system for visualization and measurement of teeth on the basis of X-ray images. The input to the system are sequences of images representing 2D slices of jaws. On their basis 3D image is constructed (interpolated) which can be manipulated in 3D space using any rotations, scaling or shifts. As a result 2D image is obtained which is a projection of 3D image on the observer's plane. Additional functionality of the system include advanced and computer aided measurement of surface areas or volumes of selected teeth structures in three dimensions.

Knowledge modeling and usage

Intelligent knowledge acquisition and active contours generalizations(A. Tomczyk, P. S. Szczepaniak, M. Pryczek)

Non-trivial methods of object localization and recognition systems require a additional expert knowledge to be used. Modern soft computing and machine learning methods allow to acquire that knowledge from even non-technical experts.


Active contours and their generalizations (active partitions) are a new methodology in image content analysis. Both of them can easily use expert knowledge to localize and recognize objects (object identification, image categorization, video tracking, etc.).

(D. Szajerman, J.

The term responsive environment means mapping of real-world environment parameters, such as lighting or temperature to virtual-world conditions affecting the rendering and application logic.

Whole research takes into account mobile devices with a set of sensors and external embedded devices like Arduino which expand this set with additional elements (e.g. humidity sensor).
