We describe results of time- and frequency-difference imaging experiments using a 16-channel KHU Mark1 EIT system operating in the frequency range of 10 Hz to 500 kHz. As imaging objects, we used a saline tank including three objects of banana, cucumber, and Perspex. Reconstructed images showed frequency-dependent conductivity and permittivity changes of the objects. Following the tank experiment, we performed a difference imaging experiment of a canine thorax during controlled ventilation. For a human subject, we tried difference imaging of the thorax during normal ventilation and the abdomen after intake of conductive liquid. Nothing that both σ and ε affect real and imaginary parts of measured boundary voltages, we suggest future works of new methods to reconstruct and interpret reconstructed difference images of σ and ωε.

This paper presents a new approach to the realistic rendering of facial skin and to the transform of bare-skin colors into make-up ones based on the BTF measurement from 2D photographs. We develop an apparatus to capture skin texture images under various lighting and viewing directions. Instead of physical modeling of human skin layers, our approach is based on the BTF (Bidirectional Texture Function) for skin texture generation and rendering. We present a method to add make-up effects to bare skin using a color transformation between the BTFs of bare skin and skin with make-up. Experimental results demonstrate that the presented method generates realistic skin texture and cosmetic effects. [ABSTRACT FROM AUTHOR]
