Covert Tracking to Immersive Stimuli in Traumatic Brain Injury Subjects With Disorders of Consciousness.

Eye tracking assessments are clinician dependent and can contribute to misclassification of coma. We investigated responsiveness to videos with and without audio in traumatic brain injury (TBI) subjects using video eye-tracking (VET). We recruited 20 healthy volunteers and 10 unresponsive TBI subjects.

Covert Tracking to Visual Stimuli in Comatose Patients With Traumatic Brain Injury.

Objectives: This study investigated video eye tracking (VET) in comatose patients with traumatic brain injury (TBI).

Methods: We recruited healthy participants and unresponsive patients with TBI. We surveyed the patients' clinicians on whether the patient was tracking and performed the Coma Recovery Scale-Revised (CRS-R).

Remote Data Collection During a Pandemic: A New Approach for Assessing and Coding Multisensory Attention Skills in Infants and Young Children.

In early 2020, in-person data collection dramatically slowed or was completely halted across the world as many labs were forced to close due to the COVID-19 pandemic. Developmental researchers who assess looking time (especially those who rely heavily on in-lab eye-tracking or live coding techniques) were forced to re-think their methods of data collection. While a variety of remote or online platforms are available for gathering behavioral data outside of the typical lab setting, few are specifically designed for collecting and processing looking time data in infants and young children.

Improved stereo matching in scattering media by incorporating a backscatter cue.

In scattering media, as in underwater or haze and fog in atmosphere, image contrast deteriorates significantly due to backscatter. This adversely affects the performance of many computer vision techniques developed for clear open-air conditions, including stereo matching, when applied to images acquired in these environments. Since the strength of the scattering depends on the distance to the scene points, the scattering field embodies range information that can be exploited for 3-D reconstruction.
