| Abstract(in English) | In this paper, we show an FPGA implementation of the Starbust algorithm without external memory, which detects an ellipse from a given input image for eye tracking. The first part of this algorithm, in which feature points for a potential contours are detected, is implemented in a deep-pipelined stream-oriented architecture. For the second part, where many ellipses are repeatedly fit and validated with the RANSAC algorithm, we compare three different architectures based on Cramer's rule, Gauss-Jordan elimination and LU decomposition. Comparison criteria include resource usage, throughput and energy consumption. As a result, our system achieved a real-time throughput of 62.5 frames per second with power consumption of approximately 3 watts. In addition, the three implementations showed different characteristics in terms of the performance, resource utilization and energy consumption, suggesting that the optimal algorithm needs to be chosen depending on the amount of resources on FPGAs and required performance. |
