Real-time object based single-stream to multi-stream network enabled multimedia system using an adder-less reconfigurable fast area correlator processor

This paper presents a network enabled reconfigurable FPGA based real-time system for selectively detecting, adding, deleting or displacing irregular shaped video objects in high-resolution video sequence obtained from a digital camera. Real-time irregular shaped object detection and insertion from a high-resolution high frame rate video requires a high performance system. The system can selectively add or delete video objects from a single video stream and produce multiple streams for broadcasting in a network. Each host in the network get a different version of the video. In this paper we present a run-time reconfigurable design of an area correlator, which is a hardware efficient technique for detecting objects in a frame. The main contribution resides in the concurrent apporach which modfies the algorithm for hardware specific implementation, novel hardware building blocks, and a set of architectures which can be mapped as reconfigurable design at runtime. This system provides flexibility in creative video enriched multimedia applications and has wide range of applications and is applicable in object detection, video recording, surveillance, conferencing, broadcasting and augmented reality.
