Original abstract
The method of fuzzy segmentation of a digital image is generalized to the framework of L-fuzzy sets. Such an approach enables the use of various user-defined criteria for comparison of pairs of objects. These criteria are merged into a single mapping whose codomain is a poset. Then a free lattice structures are introduced and the procedure of Lfuzzy equivalence generation follows. The obtained L-fuzzy partition is then transformed into the resulting sets using the process of thresholding by terms from the free lattice. Discussion on applicability and computability of the results is presented and some examples are shown. Possible ways of improvements are suggested.
Czech abstract
Metoda fuzzy segmentace digitálního obrazu je zobecněna v rámci L-fuzzy množin. Takový přístup umožňuje použití různých kritérií definovaných uživatelem pro srovnání párů objektů. Tato kritéria jsou sloučena do jediného zobrazení do uspořádané množiny. Pak se uplatní volné svazové struktury a následuje postup generování L-fuzzy ekvivalence. Získaný L-fuzzy rozklad množiny je pak transformován do výsledných množin s využitím procesu prahování termy z volného svazu. Následně je prezentována diskuse o použitelnosti a vyčíslitelnosti výsledků včetně příkladů. Navrženy jsou zde i možné způsoby zlepšení.
