This paper sets out and presents a new approach to determine the stroke volume of the artificial ventricle. The stroke volume of the chamber is one of the basic heart function parameters. For the artificial heart assist purpose, in the study this value is calculated based on the mapped shape of the flaccid membrane of the extracorporeal pneumatic heart assist pump. This is a continuation of the earlier...
There is no suitable golden standard for the detection of atypical pigment network and irregular streaks applied to skin lesion images. This information however is important in assessment of melanoma in skin dermatoscopic images. Thus there is a need for development of image analysis techniques that satisfy at least subjective criteria defined by dermatologists. In this paper we present the application...
The interaction between real and synthetic geometry is fundamental to Augmented Reality. Portraying such interactions in a manner that is convincing to the user requires 3D models of the shape of the real objects involved. The large-scale application of Augmented Reality technologies will thus require practical methods for generating 3D models of real objects. These methods will need to be fast, flexible,...
In this paper we present an optimal omnidirectional visual sensor which can replace perspective camera network for traffic diagnosis. The proposed system has the advantage, by the number and the designed mirror, to generate a single view of the crown and junction ways of the crossroads by maximizing the number of useless pixels. So, the percentage of pixels utilized directly for subsequent phases...
To realize a seamless augmented reality system, proper simulation of real lighting is an important factor. In this paper, two spheres with Lambert surface are introduced in the real scene. Through image analysis and analytical geometry of three dimensions, the illumination parameters of the real scene are estimated automatically. These parameters describe a point light source and ambient light. Using...
An ECT (eddy current testing) camera system is proposed to quantitatively evaluate/visualize cracks of the metal structures. It is composed of the multi-coil ECT probe, ECT instrument, and computer-aided analysis/visualization that correspond to the lens, film and development/picture in the elements of photography, respectively. At first, scanning the probe in one direction gives ECT signals as a...
