Query: EgoReID Dataset: Person Re-identification in Videos Acquired by Mobile
  Devices with First-Person Point-of-View   In recent years, we have seen the performance of video-based person
Re-Identification (ReID) methods have improved considerably. However, most of
the work in this area has dealt with videos acquired by fixed cameras with
wider field of view. Recently, widespread use of wearable cameras and recording
devices such as cellphones have opened the door to interesting research in
first-person Point-of-view (POV) videos (egocentric videos). Nonetheless,
analysis of such videos is challenging due to factors such as poor video
quality due to ego-motion, blurriness, severe changes in lighting conditions
and perspective distortions. To facilitate the research towards conquering
these challenges, this paper contributes a new dataset called EgoReID. The
dataset is captured using 3 mobile cellphones with non-overlapping
field-of-view. It contains 900 IDs and around 10,200 tracks with a total of
176,000 detections. The dataset also contains 12-sensor meta data e.g. camera
orientation pitch and rotation for each video.
  In addition, we propose a new framework which takes advantage of both visual
and sensor meta data to successfully perform Person ReID. We extend image-based
re-ID method employing human body parsing trained on ten datasets to
video-based re-ID. In our method, first frame level local features are
extracted for each semantic region, then 3D convolutions are applied to encode
the temporal information in each sequence of semantic regions. Additionally, we
employ sensor meta data to predict targets' next camera and their estimated
time of arrival, which considerably improves our ReID performance as it
significantly reduces our search space.
