Oversampled pyramid decompositions have been successfully applied to scalable video coding. Quantization noise feedback at the encoder closed-loop coding" has several advant...
This paper describes an approach to the extraction of articulated objects which will be used for gait analysis. In most medical applications markers are used to determine trajecto...
This paper presents an e cient scheme for a neinvariant object recognition. A ne invariance is obtained by a representation which is based on a new sampling con guration in the fr...
