An approach for comparing qualitative descriptions of shape of objects is presented in this paper. A similarity factor between shapes is determined as the number of operations required for transforming one shape into another. The possible transformational operations are defined by conceptual neighbourhood diagrams (CND). Our approach has been tested using images from the MPEG-7 CE-Shape-1 library and results show that our similarity calculus is invariant to translations, rotations and dilations and that the values ...

This concept is used in this paper to present a qualitative representational model for integrating qualitatively time and topological information for reasoning about dynamic worlds in which spatial relations between regions may change with time. The calculus here presented exploits Freksa’s notion of conceptual neighbourhood and defines a topological neighbourhood

The application consists on given an image with different objects (representing real tiles) and a vectorial image design of a ceramic tile mosaic, the application recognizes in a qualitative way which tile in the image belongs to the mosaic design and indicates its position and

pale, light and dark colours, and colours in the grey scale, and it has been parameterised by participants of a study in two universities in Spain: University Jaume I and University of Sevilla.
The relational structure of the QCD model is analysed by means of a conceptual neighbourhood diagram and it is used to formulate a measure of similarity for solving absolute and relative comparisons of qualitative colours. Moreover, a similarity measure between colour compositions, called SimQCDI, is also developed. A survey test on several art compositions is carried out and the results obtained by the participants are analysed and compared to the computational results provided by the SimQCDI. Also, a comparison to the standard RGB Colour Histogram similarity method is carried out, which shows that the proposed similarity is more intuitive and that the results obtained are similar with respect to quantification. Finally, the cognitive adequacy of the QCD model is also analysed.
