abstract = {This paper presents a vector quantization process that can be
applied online to a stream of inputs. It enables to set up and
maintain a dynamical representation of the current information in
the stream as a topology preserving graph of prototypical values,
as well as a velocity field. The algorithm relies on the
formulation of the accuracy of the quantization process, that
allows for both the updating of the number of prototypes
according to the stream evolution and the stabilization of the
representation from which velocities can be extracted. A video
processing application is presented.}
