Sift algorithms
WebSIFT is state-of-the-art for high precision feature detection but it is slow and not compatible with real-time robotic applications. Thus, in our work, we explore how to speed up SIFT algorithm for real-time robot localization by employing an unconventional computing paradigm with oscillatory neural networks (ONNs).
