Visual Snow: Visual Misperception
Journal of Neuro-Ophthalmology, 2018Background: Visual snow (VS) is a constant visual disturbance described as flickering dots occupying the entire visual field. Recently, it was characterized as the defining feature of a VS syndrome (VSS), which includes palinopsia, photophobia, photopsias, entoptic phenomena, nyctalopia, and tinnitus.

Visual proteomics attempts to generate molecular atlases by providing the position and angular orientation of protein complexes inside of cells. This is accomplished by template matching (pattern recognition), a cross-correlation-based process that matches the structure of a specific protein complex to the densities of the whole volume or subvolume of ...

Case Study: Visualizing Visualization
IEEE Symposium on Information Visualization, 2005In this case study we attempt to visualize a real-world dataset consisting of 600 recently published information visualization papers and their references. This is done by first creating a global layout of the entire graph that preserves any cluster structure present. We then use this layout as a basis to define a hierarchical clustering.

1) The eye may be regarded as an automatic camera that keeps the average sensitivity near the middle of the working range. 2) Nerve signals are contrast-coded, and hence are not changed by changes in general illumination. 3) Rod thresholds can be raised three-fold by a background from which only 1% of the rods have caught one quantum.

Visualization is a powerful method to present and analyze a large amount of data. It is increasingly important in bioinformatics and is used for exploring different types of molecular biological data, such as structural information, high throughput data, and biochemical networks.

Current practices in visual field tests require skilled eye care professionals and expensive machine setup in a controlled environment [1], thus, limit their availability within eye care clinics and hospitals. With a low-cost Virtual Reality (VR) device and its immersive capability, we developed Visual Field Visualizer (VFV), a prototype VR system that

Visual development is considered as a neurobiological process, integrated into developing systems for cognition, action and attention. The onset in early months of selective processing of orientation, motion, color and binocular vision, and of selective oculomotor control, reflect the emergence of cortical visual systems that modulate and control ...

Visualizing visual impairments
Gerontechnology, 2006We developed and evaluated methods to visualize the limitations of visually impaired persons. Three types of simulation were developed: (i) fixation independent, showing which elements remain visible after ample inspection, related to object recognition, (ii) fixation dependent, showing which elements remain visible in the entire visual field while ...

Visual imagery and visual representation
Trends in Neurosciences, 1994Among many controversies in visual neuroscience is whether visual imagery of objects, scenes and living beings is based upon contributions of the early visual areas or depends on hierarchical higher visual areas only, and whether the cortical areas subserving visual imagery are identical to those underlying visual perception.

Damage at many different locations within the visual system can result in visual deficits, and a knowledge of the anatomy involved makes it possible to understand these deficits. In this chapter, we will review the visual system from basic anatomy to the description of more complex higher visual function.
