INTRODUCTION We propose a low-cost foot scanner to replace the expensive ones. Components used in our scanner and shape acquisition method are entirely different from those of other classical foot scanners. Several PC cameras are used instead of expensive CCD cameras. Also, the suggested scanner does not require expensive moving mechanism, emitters (laser generator or pattern generator) and som...

A systematic procedure for designing a high-speed, compact serial-kinematic XYZ scanner for atomic force microscopy is presented in this Letter. Analytical stiffness calculations are used to estimate the first natural frequency and travel range of the scanner. Design and characterisation of the scanner are presented. Results of finite-element analysis and experimentation on the scanner revealed...

A scanner is developed that can capture range as well as color data from four sides of an object and combine the data into a complete model. In this scanner four synchronous cameras scan an object from four sides in a coordinate system that is attached to the scanner. Data produced by the four cameras, therefore, automatically come together without the need for image registration. The uniquenes...

Two recent studies report changes in human brain responses after exposure to psilocybin, the active ingredient of hallucinogenic mushrooms. Psilocybin increased sensory cortex responses during emotional recollection, but decreased resting-state blood flow in prefrontal cortex, with potential implications for treating depression.

This paper presents a new vulnerability scanning model named as INVUS, which contains aspects of both network and host-based vulnerability scanners. INVUS model has client/server architecture and provides an option to repair the found vulnerabilities by working with the firewall.

Color scanners are becoming quite popular as input devices for desktop publishing. In many applications it is desirable to obtain calibrated color from them. In order to properly calibrate the device for a variety of illuminants, it is necessary to estimate the spectral sensitivity of the scanner. This paper describes a set theoretic approach to this problem. This method is shown to have increa...

The proliferation of malware (viruses, Trojans, and other malicious code) in recent years has presented a serious threat to individual users, enterprises, and organizations alike. Current static scanning techniques for malware detection have serious limitations; on the other hand, sandbox testing fails to provide a complete satisfactory solution either due to time constraints (e.g., time bombs ...

We give a method for improving the resolution of surfaces captured with a laser range scanner by combining many very similar scans. This idea is an application of the 2D image processing technique known as superresolution. The input lower-resolution scans are each randomly shifted, so that each one contributes slightly different information to the final model. Noise is reduced by averaging the ...
