“…The rationale of searching for variations in the optical flow pattern has proven useful for related types of object discrimination. For example, with images acquired with a moving camera, this principle has been used to detect static objects located at different distances than a stationary background [2][3][4][5][6] . In addition, this principle has been used for detecting moving objects against a stationary background [7][8][9][10][11] .…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…time to contactlvisual threat cue [2] [9]) or computed egomotion information [5] to assist navigation. In [4] it is shown how collision points can be determined based on optical flow, though this method does not account for motion of objects in the environment. It has even been shown how motion information can be used in a driver warning system [7].…”
