Fractal Image Feature Vectors with Applications in Fractography
Result description
The relation between morphology of fatigue fracture surface and crack growth rate may be expressed, among other methods, by means of fractal analysis. Fractal dimension as a single numerical value is not sufficient. Two types of fractal feature vectors are discussed: multifractal and multiparametric. For analysis of images, the box-counting method for 3D is applied with respect to the non-homogeneity of dimensions (two in space, one in brightness). Examples of application are shown: images of several fracture surfaces are analyzed and related to crack growth rate.

Fraktální obrazové příznakové vektory s aplikacemi ve fraktografii
Czech description
Vztah mezi morfologií únavové lomové plochy a rychlostí šíření trhliny může být vyjádřen mj. pomocí fraktální analýzy. Fraktální dimenze jakožto skalární veličina nepostačuje. Jsou diskutovány dva typy fraktálních příznakových vektorů: multiparametrickýa multifraktální. Mřížková metoda ve 3D je aplikována se zřetelem k nehomogenitě dimenzí (dvě v prostoru, jedna v jasu). Aplikace je doložena příklady - obrazy několika lomových ploch jsou dány do relace s rychlostí šíření trhliny.
