the highway safety manual [hsm, 2010] recommends safety evaluations be performed beforeimplementing any roadway treatment to predict the expected safety consequences. safety consequences canbe measured using crash prediction models, crash modification factor (cmfs), or both. this paperdevelops a cmf to show the expected impact of red-light cameras (rlcs) on safety at signalizedintersections. a ...

Defocusing effects in modulation transfer function (MTF) measurement of charge coupled device (CCD) cameras is the main focus of current paper. We introduce measuring Point-spread function (PSF) in order to calculate the MTF and further more we will study the shape of MTF and its cut-off frequency by adjusting the lens focusing in different locations. A collimated white light LED by broadband s...

The ability to create an accurate three-dimensional reconstruction of a captured scene draws attention the prin- ciples light fields. This paper presents approach for field camera calibration and rectification, based on pairwise pattern-based parameters extraction. It is followed by correspondence-based algorithm refinement from arbitrary scenes using triangulation filter nonlinear optimization...
