DetCo: Unsupervised Contrastive Learning for Object Detection

Self-supervised learning of visual representation is an es-sential problem in computer vision, facilitating many down-stream tasks such as image classification, object detection, and semantic segmentation [23,35,43]. It aims to provide models pre-trained on large-scale unlabeled data for down-stream tasks. Previous methods focus on designing ...
