This document summarizes three object detection methods: CornerNet, Zhou et al., and Duan et al. CornerNet detects objects by locating corners, while Zhou et al. and Duan et al. detect objects as center points. Duan et al. achieves the highest accuracy at 47.0% for multiple scale object detection by using keypoint triplets centered around each object.
