This article describes an FPGA-based implementation of the Harris-Affine feature detector introduced by Mikolajczyk and Schmid. The system is implemented on the Transmogrifier-4, a prototyping platform that includes four Altera Stratix S80 FPGAs and NTSC/VGA video interfaces. The system achieves a speed of 90-9000 times the speed of an equivalent software implementation, allowing it to process standard video (640 x 480 pixels) at 30 frames per second.
