Tiny object detection has become an active area of research because images with tiny targets are common in several important real-world scenarios.

To successfully associate prototypes with class labels and extract a background prototype that is capable of predicting a mask for the background regions of the image, the machinery for extracting and using foreground prototypes is induced to become more discriminative between different classes.

To overcome this issue, we propose CobNet which utilises information about the background that is extracted from the query images without annotations of those images.

Inspired by how humans detect anomalies, i. e., comparing an image in question to normal images, we here leverage registration, an image alignment task that is inherently generalizable across categories, as the proxy task, to train a category-agnostic anomaly detection model.
