  HEVC (High Efficiency Video Coding) encryption, which has been proposed to encrypt intraprediction modes (structural information), transform coefficients (texture information) and motion related codewords (motion information), has received considerable attention recently. However, there is still the issue of efficiency when HEVC encryption is applied in the Internet of Multimedia Things (IoMT). Ai... View full abstract»

  This paper proposes a scalable approach for counting pedestrians crossing a virtual line when the crowd is highly dynamic and possibly extremely dense. The approach mainly consists of two parts: local crowd density estimation and pedestrian counting based on accumulating local densities across the line. To obtain a fine estimation of local crowd densities, we divide the neighborhood at the line in... View full abstract»
