| Abstract(in English) | This paper shows stream-oriented FPGA implementation of the Features from Accelerated Segment Test (FAST) corner detection, which is used in the parallel tracking and mapping (PTAM) for augmented reality (AR). The matching process with a large number of corner patterns is one of the problems for implementing machine-learned FAST corner detection on an embedded hardware system like FPGAs. We propose compression methods of the corner patterns considering discriminant split and pattern symmetry for rotation and inversion. We proposed methods enable implementation of the machine-learned FAST corner detection with a combinational circuit. This implementation of the machine-learned FAST corner detection achieves real-time execution performance with 7-9% of available slices of a Virtex-5 FPGA. |
