Foveation principles suggested by natural vision systems enable the construction of a proper mask that may modulate the coefficients given by the Discrete Wavelet Transform of an ...
Complex shapes - such as the surface of the human brain may be represented and analyzed in frequency space by a spherical harmonics transformation. A key step of the processing ch...
The paper addresses a problem of combining XML querying with ontology reasoning. We present an extension of a rule-based XML query and transformation language Xcerpt. The extensio...
