People counting has wide applications for video surveillance. In this paper, we propose a detection and tracking based counting method. The method involves 2 steps, at the first step, a head and shoulder shape hog feature is extracted to detect pedestrians.

Gasolines of two different octane numbers are experimentally distinguished using a thin metal sheet perforated with a periodic hole array terahertz surface plasmon (SP) sensor. This sensor is proved to be very sensitive to the change in permittivities of analytes. The differences between the gasolines 93# and 97# in composition lead to various refractive(More)
