This paper describes a real time system for human computer interaction through gesture recognition and three-dimensional hand tracking. We use one camera that is focused at the user's hand, with an attached small rigid dark square. The system can recognize in real time the gesture and track the hand in three dimensions. The system uses a SIMD real time image processing board for low and interme...

cardiovascular disease remains the principal cause of death in the modernized world.   several novel noninvasive imaging techniques have been recently developed to improve diagnosis of cardiac and coronary disease.   of these advances, multidetector computed tomographic (mdct) angiography has evolved most dramatically to transform computed tomography from a single-slice trans-axial modality to ...

Following the successful application of deep convolutional neural networks to 2d human pose estimation, next logical problem solve is 3d estimation from monocular images. While previous solutions have shown some success, they do not fully utilize depth information inputs. With goal addressing this ambiguity, we build a system that takes joint locations as input along with their estimated value ...

Multimaterial 3D printing using microfluidic printheads specifically designed for seamless switching between two visco-elastic materials "on-the-fly" during fabrication is demonstrated. This approach opens new avenues for the digital assembly of functional matter with controlled compositional and property gradients at the microscale.

3D printing is a relatively new, rapidly expanding method of manufacturing that found numerous applications in healthcare, automotive, aerospace and defense industries and in many other areas. In this review, applications in medicine that are revolutionizing the way surgeries are carried out, disrupting prosthesis and implant markets as well as dentistry will be presented. The relatively new fi...

in this paper, the detection of moving targets in airborne widely separated phased multiple input multiple output (mimo) radars which are located on moving platform is investigated. in order to derive the detector, the generalized likelihood ratio test is applied. the proposed detection rule, exploits the clutter subspace information and its maximum likelihood estimation, to improve the detecti...

This paper describes a framework for constructing a three-dimensional immersive environment that can be used for training physical activities. The system is designed to capture three dimensional full-body human motion in real time and visualize the data either locally or remotely through three-dimensional display system so that the data can be viewed from arbitrary viewpoints. In the proposed s...

This paper addresses the problem of computing the camera motion and the three-dimensional structure of a scene using two uncalibrated images as inputs. The camera motion is calculated by estimating the essential matrix and using approximate values, easily available, for the intrinsic parameters. The classical eight-point algorithm to calculate the essential matrix is known to be very sensitive ...
