Object re-identification (ReID) is a key application of city-scale cameras. While classic ReID tasks are often considered as image retrieval, we treat them as spatiotemporal queries for locations and times in which the target object appeared. Spatiotemporal reID is challenged by the accuracy limitation in computer vision algorithms and the colossal videos from city cameras. We present Clique, a practical ReID engine that builds upon two new techniques: (1) Clique assesses target occurrences by…

CityFlow: A City-Scale Benchmark for Multi-Target Multi-Camera Vehicle Tracking and Re-Identification

This work introduces CityFlow, a city-scale traffic camera dataset consisting of more than 3 hours of synchronized HD videos from 40 cameras across 10 intersections, with the longest distance between two simultaneous cameras being 2.5 km.

Multi-camera vehicle tracking and re-identification based on visual and spatial-temporal features

A novel framework for multi-camera tracking, which integrates visual features, orientation prediction and temporal-spatial information of the trajectories for optimization is proposed, which achieves the first place in vehicle re-identification at the NVIDIA AI City Challenge 2019.

Multi-View Vehicle Re-Identification using Temporal Attention Model and Metadata Re-ranking

This paper proposes a viewpoint-aware temporal attention model for vehicle ReID utilizing deep learning features extracted from consecutive frames with vehicle orientation and metadata attributes being taken into consideration and achieves mAP of 79.17% with the second place ranking in the competition.

Vehicle Re-Identification with Location and Time Stamps

This paper introduces an ensemble technique to combine the informative cues of multiple Re-ID models effectively and builds up a system to acquire the vehicle location and time stamps.

Scalable Person Re-identification: A Benchmark

A minor contribution, inspired by recent advances in large-scale image search, an unsupervised Bag-of-Words descriptor is proposed that yields competitive accuracy on VIPeR, CUHK03, and Market-1501 datasets, and is scalable on the large- scale 500k dataset.

You Only Look Once: Unified, Real-Time Object Detection

Compared to state-of-the-art detection systems, YOLO makes more localization errors but is less likely to predict false positives on background, and outperforms other detection methods, including DPM and R-CNN, when generalizing from natural images to other domains like artwork.

VideoEdge: Processing Camera Streams using Hierarchical Clusters

This work proposes VideoEdge, a system that introduces dominant demand to identify the best tradeoff between multiple resources and accuracy, and narrows the search space by identifying a "Pareto band" of promising configurations.

Person Re-identification: Past, Present and Future

The history of person re-identification and its relationship with image classification and instance retrieval is introduced and two new re-ID tasks which are much closer to real-world applications are described and discussed.

ReXCam: Resource-Efficient, Cross-Camera Video Analytics at Enterprise Scale

ReXCam exploits spatial and temporal locality in the dynamics of real camera networks to guide its inferencetime search for a query identity, and builds a cross-camera correlation model that encodes the locality observed in historical traffic patterns.

Horizontal Pyramid Matching for Person Re-identification

A simple yet effective Horizontal Pyramid Matching (HPM) approach to fully exploit various partial information of a given person, so that correct person candidates can be still identified even even some key parts are missing.
