The K2 Summit camera was initially the only commercially available direct electron detection camera that was optimized for high-speed counting of primary electrons and was also the only one that implemented centroiding so that the resolution of the camera can be extended beyond the Nyquist limit set by the physical pixel size. In this study, we used well-characterized two-dimensional crystals o...

In this article a method for reconstructing atmospheric cloud surfaces using a stereo camera system is presented. The proposed camera system utilizes fish-eye lenses in a flexible wide baseline camera setup. The entire workflow from the camera calibration to the creation of the 3D point set is discussed, but the focus is mainly on cloud segmentation and on the image processing steps of stereo r...

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...

Realistic simulation of smoke is used in the special effects industry to produce smoke in both feature films and video games. Traditional simulations utilize uniformly spaced rectangular computational grids to perform the smoke simulation. Various changes had been proposed to improve different aspects of the simulation, including level of details, memory usage and simulation speed. In this thes...

This paper presents speed estimation of a moving object thanks to two images captured within a known time interval from one stationary uncalibrated camera. The development is currently applicable to rigid objects animated by a pure translation and requires the localization of corresponding points in both images and the specification of one real dimension. An interesting solution based on an equ...

In this paper, we present a new technology to track multiple active Tangible User Interfaces (TUI) on a projection table. We use a commercial high speed infrared tracking camera with modified firmware. With a special tracking method, we reach update rates of up to 250 Hz with low latencies. At this tracking rate, we are able to track the position, state and the orientation of more than 10 activ...

Farming organic vegetable and crops have grown as a market desiring commodity. Weed control in farms has been costly and laborous and it has always been hard to achieve a proper weeding. A few chemicals are commonly applied in organic farming. Thermal weeding with flame burners seems a good solution; however, it has its own drawbacks, such as; damaging the main crops, low performance, being inf...

The blurred images will make image processing difficult and be hard to get high image solution for recognition, which will lower the precision of a variable rate spray system in pesticide application. In this paper, Radon transform in frequency domain is used in this work to test the blur angle and blur length in different tractors speeds and camera heights. Four image restoration methods in te...
