Robustness of SAM: Segment Anything Under Corruptions and Beyond
share
Segment anything model (SAM), as the name suggests, is claimed to be capable of cutting out any object. SAM is a vision foundation model which demonstrates impressive zero-shot transfer performance with the guidance of a prompt. However, there is currently a lack of comprehensive evaluation of its robustness performance under various types of corruptions. Prior works show that SAM is biased towards texture (style) rather than shape, motivated by which we start by investigating SAM's robustness against style transfer, which is synthetic corruption. With the effect of corruptions interpreted as a style change, we further evaluate its robustness on 15 common corruptions with 5 severity levels for each real-world corruption. Beyond the corruptions, we further evaluate the SAM robustness on local occlusion and adversarial perturbations. Overall, this work provides a comprehensive empirical study on the robustness of the SAM under corruptions and beyond.
