Public camera feeds are increasingly being opened to use by multiple authorities (e.g., police, fire, traffic) as well as to the public. Because of the difficulty and insecurity of sharing cryptographic keys, these data are available in the clear. However, authorities must have a mechanism to assure trust in the video, that is, to authenticate it. While lossless video is straightforward to authenticate...
This paper introduces a method for the efficient comparison and retrieval of near duplicates of a query video from a video database. The method generates video signatures from histograms of orientations of optical flow of feature points computed from uniformly sampled video frames concatenated over time to produce time series, which are then aligned and matched. Major incline matching, a data reduction...
The lack of real-time tools capable of detecting risk of blackouts is one of the contribution factors to the recent large blackouts occurred around the world. In terms of dynamic security assessment (DSA), artificial intelligence and data mining techniques have been widely applied to facilitate very fast DSA for enhanced situational awareness of insecurity. However, many of the current state-of-the-art...
In this work we have demonstrated, for the first time, a 0.605μm2 dual core oxide (DCO) dual Vdd 8T SRAM cell in 45 LPG triple gate oxide CMOS process for use as L1 cache for high performance low leakage mobile applications. The DCO 8T SRAM operates under dual voltage supplies with write assist. Compared to traditional single-end 8T cell, DCO 8T SRAM showed the same performance with only half the...
