An Uncertainty-Aware Performance Measure for Multi-Object Tracking

نویسندگان

چکیده

Evaluating the performance of multi-object tracking (MOT) methods is not straightforward, and existing measures fail to consider all available uncertainty information in MOT context. This can lead practitioners select models which produce estimates lower quality, negatively impacting any downstream systems that rely on them. Additionally, most have hyperparameters, makes comparisons different trackers less straightforward. We propose use negative log-likelihood (NLL) posterior given set ground-truth objects as a measure. measure takes into account sound mathematical manner without hyperparameters. provide efficient algorithms for approximating computation NLL several common algorithms, show some cases it decomposes approximates widely-used GOSPA metric, illustrative examples highlighting advantages comparison other measures.

Convolutional Gating Network for Object Tracking

Object tracking through multiple cameras is a popular research topic in security and surveillance systems especially when human objects are the target. However, occlusion is one of the challenging problems for the tracking process. This paper proposes a multiple-camera-based cooperative tracking method to overcome the occlusion problem.  The paper presents a new model for combining convolutiona...

Self-aware Object Tracking in Multi-Camera Networks

This chapter discusses another example of self-aware and self-expressive systems: a multi-camera network for object tracking. It provides a detailed description of how the concepts of self-awareness and self-expression can be implemented in a real network of smart cameras. In contrast to traditional cameras, smart cameras are able to perform image analysis on-board and collaborate with other ca...

Multi-camera Multi-Object Tracking

In this paper, we propose a pipeline for multi-target visual tracking under multi-camera system. For multi-camera system tracking problem, efficient data association across cameras, and at the same time, across frames becomes more important than single-camera system tracking. However, most of the multi-camera tracking algorithms emphasis on single camera across frame data association. Thus in o...

An Object Assignment Algorithm for Tracking Performance Evaluation

Performance evaluation of detection and tracking methods is a crucial issue. However, despite the efforts of the research community, there is still a lack of widely adopted methods, measures and benchmark data for this purpose. Most contributions have embraced pixel-based method, and do not report their results in terms of objects. The latter requires the assignment of ground truth objects to t...
