MambaOSR: Leveraging Spatial-Frequency Mamba for Distortion-Guided Omnidirectional Image Super-Resolution [PDF]

open access: yesEntropy
Omnidirectional image super-resolution (ODISR) is critical for VR/AR applications, as high-quality 360° visual content significantly enhances immersive experiences.

Spatial frequency adaptation modulates population receptive field sizes [PDF]

open access: yeseLife
The spatial tuning of neuronal populations in the early visual cortical regions is related to the spatial frequency (SF) selectivity of neurons. However, there has been no direct investigation into how this relationship is reflected in population ...

Effects of visual spatial frequency on audiovisual interaction: an event-related potential study [PDF]

open access: yesFrontiers in Neuroscience
Spatial frequency is a fundamental characteristic of visual signals that modulates the audiovisual integration behavior, but the neural mechanisms underlying spatial frequency are not well established.

Low-Spatial-Frequency Channels and the Spatial Frequency-Doubling Illusion [PDF]

open access: yesInvestigative Opthalmology & Visual Science, 2009
This study examined the number and nature of spatiotemporal channels in the region where the frequency-doubling (FD) illusion would be expected to occur at eight locations spanning the central 30 degrees of the visual field.The probability of seeing the FD illusion was examined in 17 subjects.

Eye Tracking Research on the Influence of Spatial Frequency and Inversion Effect on Facial Expression Processing in Children with Autism Spectrum Disorder

open access: yesBrain Sciences, 2022
Facial expression processing mainly depends on whether the facial features related to expressions can be fully acquired, and whether the appropriate processing strategies can be adopted according to different conditions.

Spatial Frequency Tuning of Body Inversion Effects

open access: yesBrain Sciences, 2023
Body inversion effects (BIEs) reflect the deployment of the configural processing of body stimuli. BIE modulates the activity of body-selective areas within both the dorsal and the ventral streams, which are tuned to low (LSF) or high spatial frequencies

Spatial frequency representation in V2 and V4 of macaque monkey

open access: yeseLife, 2023
Spatial frequency (SF) is an important attribute in the visual scene and is a defining feature of visual processing channels. However, there remain many unsolved questions about how extrastriate areas in primate visual cortex code this fundamental ...

Impact of Astrocytic Coverage of Synapses on the Short-Term Memory of a Computational Neuron-Astrocyte Network

open access: yesMathematics, 2022
Working memory refers to the capability of the nervous system to selectively retain short-term memories in an active state. The long-standing viewpoint is that neurons play an indispensable role and working memory is encoded by synaptic plasticity ...

Evaluating Test Image Quality as a Function of illumation [PDF]

open access: yesEngineering and Technology Journal, 2010
The optical imaging systems, do not give a perfect and ideal image. Butmostly give images with limited resolutions i.e. give images with blur edges. Thisblurring attributed to two main reasons.
