with the increase of the number of cameras installed across a video surveillance network, the ability of security staffs to attentively scan all the video feeds actually decreases. therefore, the need for an intelligent system that operates as a tracking system is vital for security personnel to do their jobs well. tracking people as they move through a camera network with non-overlapping field...

We propose a camera-based method for digital recovery of handwritings on ordinary paper. Our method is characterized by the following two points: (1) it requires no special device such as special paper other than a camera-pen to recover handwritings, (2) if the handwriting is on a printed document, the method is capable of localizing it onto an electronic equivalent of the printed document. The...

The main goal of this work is to find a suitable method for calculating the best setting of a stereo pair of cameras that are viewing the scene to enable spatial imaging. The method is based on a geometric model of a stereo pair cameras currently used for the acquisition of 3D scenes. Based on selectable camera parameters and object positions in the scene, the resultant model allows calculating...

Axons allow nerve cells (neurons) to signal each other over long distances. Axonal projection patterns determine the organization of the central nervous system. Morphological techniques to analyse axonal projections systematically include tracing the trajectory of labelled axons, mapping the distribution of labelled axonal terminals and nerve cell bodies and reconstructing their original spatia...

This paper describes the design and performance of an image capture simulator. The general model underlying the simulator assumes that the image capture device contains multiple classes of sensors with different spectral sensitivities and that each sensor responds in a known way to irradiance over most of its operating range. The input to the simulator is a set of narrow-band images of the scen...

technology advancement improves the way we interact with computer systems. keyboard, mouse, and touchpad provide an easier and more natural way of interaction with a computer system. nowadays, by introducing low cost and high performance depth cameras like kinect and xtion, new opportunities are available for creating even more natural interfaces. in this paper, a new model was demonstrated for...

nowadays, the subject of vision metrology network design is local enhancement of the existing network. in the other words, it has changed from first to third order design concept. to improve the network, locally, some new camera stations should be added to the network in drawback areas. the accuracy of weak points is enhanced by the new images, if the related vision constraints are satisfied si...
