A novel low-power embedded object recognition system working at multi-frames per second (Extended abstract)

Abstract

One very important challenge in the field of multimedia is the implementation of fast and detailed Object Detection and Recognition systems. In particular, in the current state-of-the-art mobile multimedia systems, it is highly desirable to detect and locate certain objects within a video frame in real time. In this paper, we present a novel FPGA-based embedded implementation of a very efficient object recognition algorithm called Receptive Field Cooccurrence Histograms Algorithm(RFCH). Our main focus was to increase its performance so as to be able to handle the object recognition task of today's highly sophisticated embedded multimedia systems while keeping its energy consumption at very low levels. Our low-power embedded reconfigurable system is at least 15 times faster than the software implementation on a low-voltage high-end CPU, while consuming at least 60 times less energy. Our novel system is also 88 times more energy efficient than the recently introduced low-power multi-core Intel devices which are optimized for embedded systems.
