Distortion introduced in radionuclide camera views by multiformat imagers

CHANGING OF STUDENTS\' VIEWS TOWARD ADDICTION BY SELF -INTRODUCED DRUG ABUSERS AND THEIR FAMILIES

A group of high school students attended 7 educational sessions for a preventive drug abuse program. The students were exposed to drug abusers and their families. Drug abusers and their families informed the subjects about the consequences of addiction in their life: how they became addicted and how the addiction worsened their psychosocial life. Moreover their families explained to student...

Quantifying the Maximum Phase-Distortion Error Introduced by Signal Samplers

Quantifying the errors introduced by signal sampler imperfections is of interest to people who are doing frequency domain measurements. The phase-distortion introduced by the sampler is hard to quantify and is usually neglected. In this article upper bounds for this phase-distortion error are derived which are based upon simple assumptions, namely that the sampler weighting function is strictly...

Modelling Scattering Distortion in 3d Range Camera

A time-of-flight camera suffers from significant range distortion due to the scattering artefact caused by secondary reflections occurring between the lens and the image plane. The reflected beam from the foreground objects undergoes multiple reflections within the camera device thereby introducing parasitic signals that bias the late-arrival, backscattered signals from the background targets. ...

Recognizing People in Non-Intersecting Camera Views

Many studies have now confirmed that it is possible to recognize people by the way they walk. As yet there has been little formal study of identity tracking using gait over different camera views. We present a new approach for people tracking and identification between different non-intersecting uncalibrated cameras based on gait analysis. An identification signature is derived from gait kinema...
