—A texture analyzing method based on a model that composes a texture of an arrangement of similar grains has been proposed. It estimates a typical shape representing the grains, called primitive, and the arrangement based on the model. This paper proposes a method of estimation based on mathematical morphology and the minimum description length (MDL)… (More)
We introduce the notion of 'Composition', 'Union' and 'Division' of cellular automata on groups. A kind of notions of compositions was investigated by Sato (1994) and Manzini (1998) for linear cellular automata, we extend the notion to general cellular automata on groups and investigated their properties. We observe the all unions and compositions generated… (More)
The notion of local composition of local transition rules for Cellular Automaton (CA for short) on groups was introduced in a straightforward way to achieve compatibility with the composition of global transition functions. In this article, we give a Morphological interpretation of local composition.
Electroencephalograph (EEG) recordings during right and left hand motor imagery can be used to move a cursor to a target on a computer screen (such system is called BCI). Recently, we have proposed the detection method of Error Potential in order to add the fail safe function to BCI system. In this paper, feature extraction method based on morphological… (More)
