Submitted for the DAMOP15 Meeting of The American Physical Society Coincidence electron/ion imaging with a fast frame camera WEN LI, SUK KYOUNG LEE, YUN FEI LIN, STEVEN LINGENFELTER, ALEXANDER WINNEY, LIN FAN, Wayne State University — A new timeand positionsensitive particle detection system based on a fast frame CMOS camera is developed for coincidence electron/ion imaging. The system is compo...
the quest for power has formed much of the world history especially in 20th and 21st centuries. oil (energy) particularly after industrial revolution has been a tool for conquest and power and has been transformed to a geopolitical issue. from a geopolitical point of view this has been the case for the last two centuries in central asia and caucasus. central asia and caucasus has always been...
In this paper we deal with the problem of calibrating a rotating and zooming camera, without 3D pattern, whose internal calibration parameters change frame by frame. First, we theoretically show the existence of the calibration parameters up to an orthogonal transformation under the assumption that the skew of the camera is zero. Auto-calibration becomes possible by analyzing inter-image homogr...
let h be a separable hilbert space and let b be the set of bessel sequences in h. by using several interesting results in operator theory we study some topological properties of frames and riesz bases by constructing a banach space structure on b. the convergence of a sequence of elements in b is de_ned and we determine whether important properties of the sequence is preserved under the con...
An electronic image stabilization algorithm is proposed based on improved Sage-Husa adaptive visual smoothing. It uses visual attention features to smooth inter-frame global motions, thus resulting in stabilized sequences. Firstly, corners are detected from reference frame as feature points. Through matching features in current frame, deleting mismatched points and solving motion equations, glo...
Extracting moving objects from a video sequence is the first step of many video processing applications, including traffic monitoring and security surveillance. If the camera is fixed in the scene, we can detect moving objects by background subtraction, and many methods have been proposed for generating background images in varying illumination conditions[4, 13]. For images taken by a pan-tilt ...
it is not possible to understand developments of a country’s culture and civilization without knowing his believes and myths. whether it is north or south, east or west, planes or mountains, sahara or deserts, here in iran every corner includes valuable and precious treasures which are known all over the world, and cultural – historical objects which are found here adorn all well known museums...
The visual tracking is the major process in finding the spot of moving object over time using a camera. Object tracking is challenging task when the object moves fast relative to the frame rate. The active contour algorithm is used for tracking the object in a given frame of an image sequence. In videos particular object motion can be tracked by using stationary cameras but in moving camera the...
We propose a method for removing marked dynamic objects from videos captured with a free-moving camera, so long as the objects occlude parts of the scene with a static background. Our approach takes as input a video, a mask marking the object to be removed, and a mask marking the dynamic objects to remain in the scene. To inpaint a frame, we align other candidate frames in which parts of the mi...
