In this paper we give a natural ordering relation between distances based on 3D-neighbourhood sequences. We prove that this ordering induces a complete compact distributive lattice over the set of 3D-neighbourhood sequences.
One of the rare reasons of the non malignant superior vena cava syndrome is the thrombosis of superior vena cava. Obstruction or occlusion of central veins is one of the many complications of the more and more frequently used central venous catheters and pacemaker electrodes. The authors report a case of superior vena cava thrombosis resulting in dialysis… (More)
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)
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)
This paper addresses the problem of recognition of emotional facial gestures from static images in thumbnail resolution. More experiments are presented, a holistic and two local approaches using SVM's as classifier engines. The experimental results related to the application of our method are reported.
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)
BACKGROUND Renal function is a major predictor of vascular function and cardiovascular diseases. Little information exists about the effect of specific renal diseases on vascular function in chronic kidney diseases (CKD). METHODS One hundred and twenty patients (60 with IgA nephropathy, IgAN, and 60 with polycystic kidney disease, PKD) with CKD stages 1-4… (More)
