Before revision:  In this paper we propose  an attention-based approach that allows our model  to index into a long term memory bank constructed on a per-camera basis and aggregate contextual features from other frames to boost object detection performance on the current frame.
After revision:  In this paper we propose an attention-based approach that allows our model , Context R-CNN, to index into a long term memory bank constructed on a per-camera basis and aggregate contextual features from other frames to boost object detection performance on the current frame.
