  abstract = {Speaker-normalization and -adaptation methods are essential components
	of state-of-the-art speech recognition systems nowadays. Recently,
	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
	and -adaptation methods. We show that the integration features benefit
	from adaptation methods and significantly outperform MFCCs in matching,
	as well as in mismatching training-test conditions.},

  abstract = {In a pattern classification setup, image segmentation is achieved
	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.}
