Events consist of objects in motion. When objects move, their opaque surfaces reflect light and produce both static image structure and dynamic optic flow. The static and dynamic optical information co-specify events. Patients with age-related macular degeneration (AMD) and amblyopia cannot identify static objects because of weakened image structure. However, optic flow is detectable despite bl...

Most of what we know about what makes a face attractive and why we have the preferences we do is based on attractiveness ratings of static images of faces, usually photographs. However, several reports that such ratings fail to correlate significantly with ratings made to dynamic video clips, which provide richer samples of appearance, challenge the validity of this literature. Here, we tested ...

In prior research, preschoolers were surprisingly poor at naming the emotion purportedly signaled by prototypical facial expressions—when shown as static images. To determine whether this poor performance is due to the use of static stimuli, rather than dynamic, we presented preschoolers (3–5 years) with facial expressions as either static images or dynamic audiovisual clips. Dynamic clips pres...

360◦ video consists of images capturing the complete scene as seen from a single point in any direction. In contrast to conventional images, 360◦ images cannot be natively represented in a planar fashion. Consequently, video created from a sequence of 360◦ images suffers from geometric distortions. These are caused by mapping of the images from a sphere in 3D space to a planar image. This paper...

BACKGROUND The most definitive diagnosis of neck pain caused by facet joints can be obtained through cervical medial branch blocks (CMBBs). However, intravascular injections need to be carefully monitored, as they can increase the risk of false-negative blocks when diagnosing cervical facet joint syndrome. In addition, intravascular injections can cause neurologic deficits such as spinal infarc...
