Query: A Flow-Guided Mutual Attention Network for Video-Based Person
  Re-Identification   Person Re-Identification (ReID) is a challenging problem in many video
analytics and surveillance applications, where a person's identity must be
associated across a distributed non-overlapping network of cameras. Video-based
person ReID has recently gained much interest because it allows capturing
discriminant spatio-temporal information from video clips that is unavailable
for image-based ReID. Despite recent advances, deep learning (DL) models for
video ReID often fail to leverage this information to improve the robustness of
feature representations. In this paper, the motion pattern of a person is
explored as an additional cue for ReID. In particular, a flow-guided Mutual
Attention network is proposed for fusion of image and optical flow sequences
using any 2D-CNN backbone, allowing to encode temporal information along with
spatial appearance information. Our Mutual Attention network relies on the
joint spatial attention between image and optical flow features maps to
activate a common set of salient features across them. In addition to
flow-guided attention, we introduce a method to aggregate features from longer
input streams for better video sequence-level representation. Our extensive
experiments on three challenging video ReID datasets indicate that using the
proposed Mutual Attention network allows to improve recognition accuracy
considerably with respect to conventional gated-attention networks, and
state-of-the-art methods for video-based person ReID.
