  	theory of invariant integration. The invariant-integration features
  	are derived from an extended time period, and their computation has
  	a very low complexity. Recognition experiments show a superior performance
  	of the presented feature type compared to cepstral coefficients using
  	a mel filterbank (MFCCs) or a gammatone filterbank (GTCCs) in matching
  	as well as in mismatching training-testing conditions. Even without
  	any speaker adaptation, the presented features yield accuracies that
  	are larger than for MFCCs combined with vocal tract length normalization
  	(VTLN) in matching training-test conditions. Also, it is shown that
  	the invariant-integration features (IIFs) can be successfully combined
  	with additional speaker-adaptation methods to further increase the
  	accuracy. In addition to standard MFCCs also contextual MFCCs are
  	introduced. Their performance lies between the one of MFCCs and IIFs.},

  	so-called invariant integration features were presented which are
  	motivated by the theory of invariants. While it was shown that the
  	integration features outperform MFCCs when used with a basic monophone
  	recognition system, it was left open, if their benefits still can
  	be observed when a more sophisticated recognition system with speaker-normalization
  	and/or speaker-adaptation components is used. This work investigates
  	the combination of the integration features with standard speaker-normalization

  	from adaptation methods and significantly outperform MFCCs in matching,
  	as well as in mismatching training-test conditions.},

  	by assigning each pixel to one of two classes: object or background.
  	The special case of vessel segmentation is characterized by a strong
  	disproportion between the number of representatives of each class
  	(i.e. class skew) and also by a strong overlap between classes. These
  	difficulties can be solved using problem-specific knowledge. The
  	proposed hysteresis classification makes use of such knowledge in
  	an efficient way. We describe a novel, supervised, hysteresisbased
  	classification method that we apply to the segmentation of retina
  	photographies. This procedure is fast and achieves results that comparable
  	or even superior to other hysteresis methods and, for the problem
  	of retina vessel segmentation, to known dedicated methods on similar
  	data sets.}
