Abstract:
For few-shot object detection, this work proposes a binary similarity detector (BSDet), which realizes a novel similarity-based multiple binary classification and enhances the feature margin between positive and hard negative samples. First, we revisit the classification paradigm, concluding that multiple binary classification paradigm is more suitable than multi-class classification paradigm for the few-shot task. Hence, we propose a binary similarity head (BSH) by posing the classification task as multiple binary similarity measurements rather than a multi-class prediction. Second, focusing on the hard negative samples, we propose a feature enhancement module (FEM). During training phase, the FEM can push the features of positive and hard negative samples far away from each other, and thus effectively suppresses false positives. Abundant experiments and visualizations indicate that our method achieves state-of-the-art performances on few-shot object detection tasks.
