We present algorithms to distinguish between healthy and diseased condition of the heart, based on the analysis of phonocardiograms. The software tries to mimic the decision-making process of a cardiologist by identifying heart beats (S1 and S2), finding extra sounds and murmurs while ignoring all kinds of artefacts and noise. Two different solutions have(More)
Text detection is typically the first step for any text processing such as hand-written text recognition, layout analysis, line detection, or writer identification. This paper describes a new method to detect text in images, particularly in historical document images. For a robust detection, we propose the use of the vesselness filter as a new preprocessing(More)
In this paper we introduce a new method to track deformable structures with the use of single retro-reflective markers. In addition, the robustness of the presented technique is evaluated under different situations that might be faced during a navigated open liver surgery. Among them one can highlight, deformation, presence of unexpected markers,(More)
