Optical Flow Measurement using Lucas Kanade Method

Motion estimation is demanding field among researchers to compute independent estimation of motion at each pixel in most of general. Motion estimation generally known as optical or optic flow. In this paper, overview of some basic concepts of motion estimation, optical flow and Lucas kanade method has been provided by us. Lucas kanade method is one of the methods for optical flow measurement. I...

Real-Time Disk Scheduling with On-Disk Cache Conscious

Previous real-time disk scheduling algorithms assume that each disk request incurs a disk mechanical operation and only consider how to move the disk head under real-time constraints. However, with the increased capacity of on-disk cache, modern disk drives read-ahead data aggressively. Thus, the ondisk cache may service lots of requests without incurring physical disk access. By exploring the ...

Time-domain terahertz spectroscopy based on asynchronous optical sampling with femtosecond semiconductor disk laser

A terahertz time-domain spectroscopy (THz-TDS) system using an optically pumped semiconductor disk laser and high-speed asynchronous optical sampling is reported. The combination of these techniques holds considerable promise towards a compact and low-cost implementation of THz-TDS. The spectrometer offers a 333 ps time delay window scanned at 10kHz and delivers more than 1.2 THz spectral cover...

Advanced Optical Disk Storage Technology

There is a growing need within the Air Force for more and better data storage solutions. Rome Laboratory, the Air Force's Center of Excellence for C3I technology, has sponsored the development of a number of operational prototypes to deal with this growing problem. This paper will briefly summarize the various prototype developments with examples of full mil-spec and best commercial practice. T...
