A problem of peat fire risk control based on GIS-technology and mathematical modeling methods are considered in this article.

9. Physically based model of light propagation in a fabric [№3 за 2009 год]

A new original approach to simulation of light propagation in a fabric is discussed in the paper. The approach is based on a confirmed assumption that cloth yarns are scattering media. The paper proposes a way to calculate the yarn’s Bi-directional Sub-Surface Scattering Reflectance Distribution Function (BSSRDF) via a Monte-Carlo ray tracing simulation of scattering and absorption of light within yarn’s volume. Then Bi-directional Reflectance Distribution Function (BRDF) of a yarn is obtained by integrating the yarn’s BSSRDF over the yarn’s surface which is approximated by a cylinder. The elaborated method produces visually plausible results and demonstrates qualitative agreement of light scattering by virtual model of cloth and real cloth sample. The light scattering of a real cloth is acquired via direct measurement performed with a proprietary measurement apparatus.

10. Reconstruction of planar objects from microscopic images [№3 за 2009 год]
Authors: Гаганов В.А., Игнатенко А.В.

In this paper we propose a new method for 3D reconstruction of planar objects from a set of microscopic images. We present a novel unreliable depth estimates rejection procedure for shape from focus family of algorithms. Also we introduce a new method to determine if a plane can be reliably estimated from a number of points in 3D space. Results of experiments on real world data, demonstrating high precision and reliability of a proposed method, are presented.
