CoKe: Localized Contrastive Learning for Robust Keypoint Detection [PDF]

open access: yes, 2022
In this paper, we introduce a contrastive learning framework for keypoint detection (CoKe). Keypoint detection differs from other visual tasks where contrastive learning has been applied because the input is a set of images in which multiple keypoints ...
