The <i>openIP</i> open source image processing library is a set of c++ libraries providing tools for education, research and industrial purposes. The aim of the development is to fill in the gap between the academic and commercial utilization of image processing. The openIP libraries are interoperable, open source and easy to install. To provide fast codes,(More)
Previously it was assumed that nerve fibres are involved in the neurogenic inflammation induced by mechanical or chemical irriations. It has been also suggested that in diabetes mellitus the unmyelinated small diameter fibers are impaired as a result of diabetic neuropathy. Therefore, our aim was to study the alterations of the nerve processes in the(More)
Skeleton is a shape descriptor which summarizes the general form of objects. It can be expressed in terms of the fundamental morphological operations. The limitation of that characterization is that its construction based on digital disks such that cannot provide good approximation to the Euclidean disks. In this paper we define a new type of skeleton based(More)
Neuropeptide Y (NPY) immunoreactivity (-IR) was found to be present in perivascular nerves in the cat dental pulp and oral mucosa. Many ganglion cells in the superior cervical ganglion also contained NPY-IR. Ligation of the inferior alveolar or lingual nerves produced an accumulation of NPY-IR in axons proximal to the site of ligation, suggesting an(More)
With the spreading of computers the demand for user-friendly interfaces has increased. The development of techniques based on multi-modal human-computer intraction makes it possible to create systems which are more natural to use. We built Turk-2, a hybrid multi-modal chessplayer with a robot arm and a screen-based talking head. Turk-2 can not only play(More)
In this paper we present an eeective character recognition algorithm, which can be applied mainly to typeset documents. Our aim was to compose a character recognition algorithm, which can be used to recognize simple typeset documents in a fast and reliable way. To get a good result by this algorithm the input text document should contain characters from the(More)
The clinical application of laser Doppler flowmetry (LDF) provides data on the blood flow of marginal gingiva (GBF) at different dental regions. The aim of the present investigation was to study the GBF at different teeth. Ten adult subjects with good oral hygiene were involved in this experiment. In a series of experiments GBF was recorded bilaterally(More)
