The MPEG-7 video compression standard allows for multimedia metadata description. By providing robust descriptors and an effective framework for storing them, MPEG-7 is designed to provide a means of navigation through audio-visual content. In particular, MPEG-7 provides a region based shape descriptor, the Angular Radial Transform (ART), for use in image and video annotation and retrieval. For this work, an FPGA based ART extractor was designed and simulated for a Xilinx Virtex-E XCV300e in order to provide a speedup over software based extraction. The design created is capable of processing over 69,4400 pixels a minute. This design utilizes 99% of the FPGA's logical resources and operates at a clock rate of 25 MHz.
