Uncomfortable images produce non-sparse responses in a model of primary visual cortex [PDF]
Royal Society Open Science, 2015 The processing of visual information by the nervous system requires significant metabolic resources. To minimize the energy needed, our visual system appears to be optimized to encode typical natural images as efficiently as possible.

Emotional processing of natural visual images in brief exposures and compound stimuli: fMRI and behavioural studies [PDF]
, 2009 This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Can the brain register the emotional valence of brief exposures of complex natural stimuli under conditions of forward and backward masking, and under ...

A bilingual text detection in natural images using heuristic and unsupervised learning [PDF]
Journal of Artificial Intelligence and Data Mining, 2022 Digital images are being produced in a massive number every day. Acomponent that may exist in digital images is text. Textual information can beextracted and used in a variety of fields. Noise, blur, distortions, occlusion, fontvariation, alignments, and

An objective, sensitive and ecologically valid neural measure of rapid human individual face recognition [PDF]
Royal Society Open Science, 2019 Humans may be the only species able to rapidly and automatically recognize a familiar face identity in a crowd of unfamiliar faces, an important social skill. Here, by combining electroencephalography (EEG) and fast periodic visual stimulation (FPVS), we

A tilt after-effect for images of buildings: evidence of selectivity for the orientation of everyday scenes [PDF]
Royal Society Open Science, 2016 The tilt after-effect (TAE) is thought to be a manifestation of gain control in mechanisms selective for spatial orientation in visual stimuli. It has been demonstrated with luminance-defined stripes, contrast-defined stripes, orientation-defined stripes

Emotional Content Modulates Attentional Visual Orientation During Free Viewing of Natural Images
Frontiers in Human Neuroscience, 2018 Visual attention is the process that enables us to select relevant visual stimuli in our environment to achieve a goal or perform adaptive behaviors. In this process, bottom-up mechanisms interact with top-down mechanisms underlying the automatic and ...

Learning midlevel image features for natural scene and texture classification [PDF]
, 2007 This paper deals with coding of natural scenes in order to extract semantic information. We present a new scheme to project natural scenes onto a basis in which each dimension encodes statistically independent information.

Reconstructing images from their most singular fractal manifold [PDF]
, 2002 Real-world images are complex objects, difficult to describe but at the same time possessing a high degree of redundancy. A very recent study [1] on the statistical properties of natural images reveals that natural images can be viewed through different ...

Contrast discrimination in images of natural scenes [PDF]
, 2022 Contrast discrimination determines the threshold contrast required to distinguish between two suprathreshold visual stimuli. It is typically measured using sine-wave gratings.
