Initialization of Model-Based Vehicle Tracking in Video Sequences of Inner-City Intersections

摘要

A fully automatic initialization approach for 3D-model-based vehicle tracking has been developed, based on Edge-Element and Optical-Flow association. An entire automatic initialization and tracking system incorporating this approach achieves results comparable to those obtained by earlier experiments based on semi-interactive initialization, provided the assessment criteria are roughly equivalent. Experiences with a large testing sample—about 15 minutes of inner-city traffic videos—are discussed in detail.
