Synchronized Two-Camera Laser Monitor for Studying Combusting Powder Systems

External Camera Calibration for Synchronized Multi-video Systems

We present a method for external camera calibration that is simple to use and offers generality in the positioning of the cameras. This makes it very suitable for the calibration of mobile, synchronized camera setups. We use a camera graph to perform global registration which helps lifting restrictions on the camera setup imposed by other calibration methods. A further advantage is that all inf...

Camera-supervised Monitor Shading Correction for Softproofing Systems

A softproofing system is required to faithfully display color images. As the user relies on an appropriate calibration of the system, a method for the evaluation of the quality of the calibration is required. Such a method has recently been developed and allows a critical side-by-side comparison between the original sample and the reproduced monitor image by placing the original directly in fro...

channel estimation for mimo-ofdm systems

تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با ‏خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز ‏الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی ‏محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...

Laser-based Profile Monitor for Electron Beams*

High performance TeV energy electron / positron colliders (LC) are the first machines to require online, non-invasive beam size monitors for micron and submicron for beam phase space optimization. Typical beam densities in the LC are well beyond the threshold density for single pulse melting and vaporization of any material, making conventional wire scanners ineffective. Using a finely focused,...
