Evaluation of Food Fineness by the Bionic Tongue Distributed Mechanical Testing Device

Sensors, 2018
In this study, to obtain a texture perception that is closer to the human sense, we designed eight bionic tongue indenters based on the law of the physiology of mandibular movements and tongue movements features, set up a bionic tongue distributed ...

Efficient coding of natural scene statistics predicts discrimination thresholds for grayscale textures

eLife, 2020
Previously, in Hermundstad et al., 2014, we showed that when sampling is limiting, the efficient coding principle leads to a ‘variance is salience’ hypothesis, and that this hypothesis accounts for visual sensitivity to binary image statistics.

Interdependences between finger movement direction and haptic perception of oriented textures.

PLoS ONE, 2018
Although the natural haptic perception of textures includes active finger movements, it is unclear how closely perception and movements are linked. Here we investigated this question using oriented textures.

Survey of Procedural Methods for Two-Dimensional Texture Generation

Sensors, 2020
Textures are the most important element for simulating real-world scenes and providing realistic and immersive sensations in many applications. Procedural textures can simulate a broad variety of surface textures, which is helpful for the design and ...

Contrast-negation and texture synthesis differentially disrupt natural texture appearance

Frontiers in Psychology, 2012
Natural textures have characteristic image statistics that make them discriminable from unnatural textures. For example, both contrast-negation and texture synthesis alter the appearance of natural textures even though each manipulation preserves some ...

Image content is more important than Bouma’s Law for scene metamers

eLife, 2019
We subjectively perceive our visual field with high fidelity, yet peripheral distortions can go unnoticed and peripheral objects can be difficult to identify (crowding). Prior work showed that humans could not discriminate images synthesised to match the

Pleasantness emotions and neural activity induced by the multimodal crispiness of monaka ice cream

Frontiers in Nutrition
Monaka ice cream is a frozen confection consisting of ice cream sandwiched between two wafers. Previous psychological research has reported that monaka ice cream with a relatively low moisture content delivers crispiness and enhances positive emotions ...

Tactile-to-Visual Cross-Modal Transfer of Texture Categorisation Following Training: An fMRI Study

Frontiers in Integrative Neuroscience, 2018
We investigated the neural underpinnings of texture categorisation using exemplars that were previously learned either within modalities (visual training and visual test) or across modalities (tactile training and visual test).

Single Image Super-Resolution Reconstruction with Preservation of Structure and Texture Details

Mathematics, 2023
In recent years, deep-learning-based single image super-resolution reconstruction has achieved good performance. However, most existing methods pursue a high peak signal-to-noise ratio (PSNR), while ignoring the quality of the structure and texture ...

Vegetable Freshness Perception in Dementia with Lewy Bodies and Alzheimer’s Disease

Dementia and Geriatric Cognitive Disorders Extra, 2020
Introduction: Although various visual function deficits have been reported in patients with Alzheimer’s disease (AD) and dementia with Lewy bodies (DLB), vegetable freshness perception has not been thoroughly examined. Objective: To investigate vegetable
