• Title: Incorporating Data Uncertainty in Object Tracking Algorithms
• Authors: Anish Muthali, Forrest Laine, Claire Tomlin
• Abstract summary: Object tracking methods rely on measurement error models, typically in the form of measurement noise, false positive rates, and missed detection rates. For detections generated from neural-network processed camera inputs, measurement error statistics are not sufficient to represent the primary source of errors. We investigate incorporating data uncertainty into object tracking methods such as to improve the ability to track objects, and particularly those which out-of-distribution w.r.t. training data.

• Abstract: Methodologies for incorporating the uncertainties characteristic of data-driven object detectors into object tracking algorithms are explored. Object tracking methods rely on measurement error models, typically in the form of measurement noise, false positive rates, and missed detection rates. Each of these quantities, in general, can be dependent on object or measurement location. However, for detections generated from neural-network processed camera inputs, these measurement error statistics are not sufficient to represent the primary source of errors, namely a dissimilarity between run-time sensor input and the training data upon which the detector was trained. To this end, we investigate incorporating data uncertainty into object tracking methods such as to improve the ability to track objects, and particularly those which out-of-distribution w.r.t. training data. The proposed methodologies are validated on an object tracking benchmark as well on experiments with a real autonomous aircraft.

  We introduce an additional graph input to the detector, where the graph represents the deployment context prior. During the test phase, any suitable deployment context prior can be injected into the detector via graph edits. Even if the deployment prior is unknown, the detector can self-calibrate using deployment prior approximated using its own predictions.

  We formulate three object detection tasks for insulator and asset inspection from aerial images, focusing on incipient faults in disks. We curate a large reference dataset of insulator images that can be used to learn robust features for detecting healthy and faulty insulators. The results suggest that object detection models can be used to detect faults in insulators at a much incipient stage.

We call it CertainNet, and it is the first to provide separate uncertainties for each output signal: objectness, class, location and size.

We propose Jaccard IoU as a new evaluation metric that extends IoU by incorporating label uncertainty.

  We propose a detection framework based on simultaneous classification and tracking in the point stream. In this framework, a tracker performs data association in sequences of the point cloud, guiding the detector to avoid redundant processing. Experiments were conducted on the benchmark dataset, and the results showed that the proposed method outperforms original tracking-by-detection approaches.
