Vytvořená aplikace je schopna vyhodnotit fraktálové dimenze pomocí několika základních metod fraktálové geometrie za výrazného snížení uživatelova vstupu do obrazové analýzy. Současně bylo zahrnuto vyhodnocení spolehlivosti proložené funkce metodou nejmenších čtverců pro odhad fraktálové dimenze. Implementované modifikace výpočtu fraktálové dimenze umožňují nové zlepší klasifikace sobě podobných struktur.

Evaluation of fractal dimensions from bitmap image (Part: Algorithms)

The work assembled the complex application for evaluation of main fractal characteristics from input image. New simple modifications of evaluation of positive cells according to appropriate scale were implemented. Detail description of theory for each method and description of evaluation process was included. Filtration modification (which is able to estimate the structure which belongs only to specified scale) was introduced together with volumetric modification that allows selecting of optional ratio for determination of positive cells. Also, Richardson method and Slit-Island method were converted to algorithm form. Program was compiled for processing of the following projects about influence between fractal dimensions and mechanical properties of tested materials.

Keywords: fractal dimension, algorithm, wood, program application
