While training at a basic object level resulted in improved encoding of coarse visual features, training at a subordinate level resulted in additional encoding of more fine-grained visual object features.
A quick scan of his last 10 days online reveals a chaotic mix of Oscars commentary, support for Colombian athletes, and coarse visual gags.
The world, the filmmakers say again and again, is a terrible place, and yet, as you look at this film, with its beautifully bleached-out palette and somewhat coarse visual texture — the images look as if they had been lightly sandpapered — it's hard not to be struck by its loveliness.
LV users were also asked if they would like to receive some coarse visual feedback.
D. Visual output (for LV users) Since mobile devices are usually equipped with a visual display screen, participants with some residual vision were asked if they would like to receive coarse visual feedback on the screen depicting the locations of detected obstacles and their distances from the user.
Taken together, these findings suggest that the amygdala performs the processing for emotional facial expressions using coarse visual inputs via the subcortical pathways, and processes eye gazes and faces with fine-grained visual information processed through the cortical visual areas (Fig. 2, left and center).
In the visual system, a coarse but structured representation of the visual field, known as a retinotopic map, is established shortly after retinal axons reach their targets, the lateral geniculate nucleus of the thalamus (LGN) and the superior colliculus (SC), even in the absence of neural activity [ 2].
Since the system is visible in visual cortex in a coarse form before the afferents carrying structured activity arrive in the superficial layers, we infer that the patch system can exist independent of any imposed functional modality.
One mechanism sets up temporary representations of objects, providing a coarse representation of their properties and allowing the visual system to individuate each element as being separate from others.
At a coarse segmentation (k=2), we observed a parcellation of visual cortex in individual subjects that reflects a foveal / peripheral distinction (note: this distinction is within our retinotopic maps, not outside like the ICA analyses).
As a result of these operations, a coarse representation of the relevant objects becomes available, allowing the visual system to individuate them in the visual field.
