• Abstract:
  Non-intrusive video imaging sensors are commonly used in traffic monitoring ; and surveillance. For some applications it is necessary to transmit the video ; data over communication links. However, due to increased requirements of ; bitrate this means either expensive wired communication links or the video ; data being heavily compressed to not exceed the allowed communications ; bandwidth. Current video imaging solutions utilize aging video compression ; standards and require dedicated wired communication lines. Recently H.264 ; (a newer standard) has been proposed to be used in transportation appli- ; cations. However, most video compression algorithms are not optimized for ; traffic video data and do not take into account the possible data analysis that ; will follow either in real time at the control center or online. As a result of ; compression, the visual quality of the data may be low, but more importantly, ; as our research efforts in vehicle tracking has shown, the tracking accuracy ; and efficiency is severely affected. iTRAC aims to inject highway content- ; awareness in the H.264 encoding standard. Our technology operates within ; the computational limits of consumer grade hardware equipment. With the ; possible reduction in bitrate we envision that we can provide a portable, easy ; to deploy, low cost, low power, wireless video imaging sensor.
