Pick-Object-Attack: Type-Specific Adversarial Attack for Object Detection

1 code implementation5 Jun 2020 Omid Mohamad Nezami, Akshay Chaturvedi, Mark Dras, Utpal Garain

We specifically aim to attack the widely used Faster R-CNN by changing the predicted label for a particular object in an image: where prior work has targeted one specific object (a stop sign), we generalise to arbitrary objects, with the key challenge being the need to change the labels of all bounding boxes for all instances of that object type.
