Gärdenfors I 121
Perception/Marr/Nishihara/Gärdenfors: (Marr & Nishihara, 1978)(1): in order to describe biological forms, cylindrical basic elements are used, in particular for the fingers, hand, arm, thorax, leg and head. In addition, there are typical angles in which the shapes stand together and typical length ratios.
I 122
The vector coordinates for the cylinders and their connecting points constitute a multidimensional space of shapes. Each cylinder corresponds to one point. A metric may be created e.g. through the use of weighted sums over all dimensions at different levels.
In this multidimensional shape space, typical shapes, e.g. of animals can be distinguished. The individual animal types form regions in this space.
