With the wide-spread availability of advanced digital cameras dermoscopy has become nowadays a standard technique to help the doctors taking diagnosis for many types of skin lesions. Further, computer-assisted techniques and image processing methods can be used for image filtering and for feature extraction and pattern recognition in the selected images. Apart from standard approaches based on ...

This paper compares color imaging principles and techniques of color quantification symbolizing the scheme of reality, human vision, and computer vision in analogy to the additive primaries red, green, and blue, respectively. The certain but unknown reality is not covered completely neither by human nor by computer vision. Up to now, most image processing techniques are designed to fit computer...

The researcher I user of software for digital image analysis is confronted with huge libraries of subroutines. In order to solve a problem from a set of problems, it is, in general, not clear which subroutines should be selected, with what setting of the parameters, The authors have set out to structure and classify subroutines generally available in image processing and image analysis librarie...

In this paper we present a semi-automatic system for the analysis of echocardiographic image sequences, able to provide useful information to cardiologists. The proposed approach combines well known techniques for the detection of left ventricular boundaries with the computation of optical ow. The initial detection of the cavity contour is based on an improved balloon model, the computation of ...

The studies in aerial vehicles modeling and control have been increased rapidly recently. In this paper , a coordination of two types of heterogeneous robots , namely unmanned aerial vehicle (UAV) and unmanned ground vehicle (UGV) is considered. In this paper the UAV plays the role of a virtual leader for the UGVs. The system consists of a vision- based target detection algorithm that uses the ...

One of the most fundamental features of digital image and the basic steps in image processing, analysis, pattern recognition and computer vision is the edge of an image where the preciseness and reliability of its results will affect directly on the comprehension machine system made objective world. Several edge detectors have been developed in the past decades, although no single edge detector...

The field of computer-assisted diagnostics is a discipline which has emerged as a result of sustained efforts throughout the clinical and scientific communities to devise systematic procedures and protocols to support physicians in rendering more informed diagnostic decisions. One of the most active and exciting branches of this research focuses on the automated interpretation of medical images...
