iTASK - Intelligent Traffic Analysis Software Kit

CVPR AI City Challenge 2020 (HCMUS Team)

Introduction

Our Intelligent Traffic Analysis Software Kit (iTASK) aims to tackle three challenging problems: vehicle flow counting, vehicle re-identification, and abnormal event detection. Experiments on the datasets of traffic flow analysis from AI City Challenge 2020 show our competitive results.

Vehicle Flow Counting

We propose to real-time track vehicles moving along the desired direction in corresponding motion-of-interests (MOIs). Our proposed method achieved S1 score of 0.8297 for vehicle flow counting in Track 1.

Vehicle Re-identification

We consider each vehicle as a document with multiple semantic words (i.e., vehicle attributes) and transform the given problem to classical document retrieval. Our proposed method achieved mAP score of 0.3882 for vehicle re-identification in Track 2.

Abnormal Event Detection

We propose to forward and backward refine anomaly detection using GAN-based future prediction and backward tracking completely stalled vehicle or sudden-change direction, respectively. Our proposed method achieved S4 score of 0.9059 for anomaly detection in Track 4.
