The Effect of Fearful Expressions on Multiple Face Tracking

open access: yesPsychologica Belgica, 2015
How does the visual system realize dynamic tracking? This topic has become popular within cognitive science in recent years. The classical theory argues that multiple object tracking is accomplished via pre-attention visual indexes as part of a ...

ONBOARD VISUAL TRACKING FOR UAV’S [PDF]

open access: yesScientific Journal of Silesian University of Technology. Series Transport, 2019
Target tracking is one of the most common research themes in Computer vision. Ideally, a tracking algorithm will only once receive information about the target to be tracked and will be fast enough to identify the target in the remaining frames ...

Visual learning in multiple-object tracking. [PDF]

open access: yesPLoS ONE, 2008
Tracking moving objects in space is important for the maintenance of spatiotemporal continuity in everyday visual tasks. In the laboratory, this ability is tested using the Multiple Object Tracking (MOT) task, where participants track a subset of moving ...

Visual Multiple-object Tracking Algorithm Based on Motion Consistency

open access: yesKongzhi Yu Xinxi Jishu, 2023
The visual multiple-object tracking module is a key component of an active onboard obstacle detection system. However, the most of currently used visual multiple-object tracking algorithms rely on offline calculation for object detection, without ...

State of the Art: Eye-Tracking Studies in Medical Imaging

open access: yesIEEE Access, 2018
Eye-tracking-the process of measuring where people look in a visual field-has been widely used to study how humans process visual information. In medical imaging, eye-tracking has become a popular technique in many applications to reveal how visual ...

Probabilistic Regression for Visual Tracking [PDF]

open access: yes2020 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2020
Visual tracking is fundamentally the problem of regressing the state of the target in each video frame. While significant progress has been achieved, trackers are still prone to failures and inaccuracies. It is therefore crucial to represent the uncertainty in the target estimation.

GRADE: A Generalization Robustness Assessment via Distributional Evaluation for Remote Sensing Object Detection

open access: yesRemote Sensing
The performance of remote sensing object detectors often degrades severely when deployed in new operational environments due to covariate shift in the data distribution. Existing evaluation paradigms, which primarily rely on aggregate performance metrics
