'Francesca Ng' 'Bal Sanghera' 'Balaji Ganeshan' 'Kenneth A. Miles' 'Gary J. Cook' 'Vicky Goh'] Background Tumor spatial heterogeneity is an important prognostic factor, which may be reflected in medical images Methods Image texture analysis is an approach of quantifying heterogeneity that may not be appreciated by the…

Sound textures, such as crackling fire or chirping crickets, represent a broad class of sounds defined by their homogeneous temporal structure. It has been suggested that the perception of texture is mediated by time-averaged summary statistics measured from early auditory representations. In this study, we…

Texture analysis is a major task in many areas of computer vision and pattern recognition, including biological imaging. Indeed, visual textures can be exploited to distinguish specific tissues or cells in a biological sample, to highlight chemical reactions between molecules, as well as to detect subcellular patterns…

Previously, in [1], 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. Here, using extensive new psychophysical data and image analysis, we show that this hypothesis…

The primate visual system analyzes statistical information in natural images and uses it for the immediate perception of scenes, objects, and surface materials. To investigate the dynamical encoding of image statistics in the human brain, we measured visual evoked potentials (VEPs) for 166 natural textures and their…

'Alice Porebski' 'Jérôme Gilles'] Complexity is one of the major attributes of the visual perception of texture. However, very little is known about how humans visually interpret texture complexity. A psychophysical experiment was conducted to visually quantify the seven texture attributes of a series of textile…

Perceived ‘Texturality’ in Natural Images Authors: ['Fumiya Kurosawa' 'Taiki Orima' 'Kosuke Okada' 'Isamu Motoyoshi'] The visual system represents textural image regions as simple statistics that are useful for the rapid perception of scenes and surfaces. What images ‘textures’ are, however, has so far mostly been…

Natural images can be seen as patchworks of different textures for which local image statistics are roughly stationary within confined regions but otherwise can be highly diverse. In order to model the natural variety of textures, we sampled 64×64 patches of homogeneous textures from a large image database and…

Disruptions of natural texture appearance are known to negatively impact performance in texture discrimination tasks, for example, such that contrast-negated textures, synthetic textures, and textures depicting abstract art are processed less efficiently than natural textures. Presently, we examined how visual ERP…

Exemplar-based texture synthesis is the process of generating, from an input sample, new texture images of arbitrary size and which are perceptually equivalent to the sample. The two main approaches are statisticsbased methods and patch re-arrangement methods. In the first class, a texture is characterized by a…

Our visual environment is full of texture—“stuff” like cloth, bark or gravel as distinct from “things” like dresses, trees or paths—and humans are adept at perceiving subtle variations in material properties. To investigate image features important for texture perception, we psychophysically compare a recent…

How communication between neurons gives rise to natural vision remains a matter of intense investigation. The mid-level visual areas along the ventral stream, as studies in primates have shown, are selective to a common class of natural images—textures—but a circuit-level understanding of this selectivity and its link…

We study the applicability of a set of texture descriptors introduced in recent work by the author to texture-based segmentation of images. The texture descriptors under investigation result from applying graph indices from quantitative graph theory to graphs encoding the local structure of images. The underlying…

Humans sense spatial patterns through their eyes and hands. Past studies have revealed differences (as well as similarities) between vison and touch in texture processing (e.g., eye is good at detecting texture boundaries, while hand can discriminate subtle texture differences), but the underlying computational…

Texture synthesis is widely used in the field of computer graphics, vision, and image processing. In the present paper, a texture synthesis algorithm is proposed for near-regular natural textures with the help of a representative periodic pattern extracted from the input textures using distance matching function. Local…

Peripheral vision comprises most of our visual field, and is essential in guiding visual behavior. Its characteristic low resolution has been explained by the most influential theory of peripheral vision as the product of representing the visual input using summary-statistics. Despite its success, this account may…

Electro-chemo-mechanical degradation pathways which significantly impact performance of ceramic (e.g., LiCoO2) battery electrodes are a strong function of bulk crystallographic texture, crystal size and interfacial misorientation angle. Via electrodeposition, deterministic synthesis of textured thick (>10 µm) films of…

Chromium Nitride thin films are known for their good mechanical properties. We present the characteristics of ultrathin Chromium Nitride films under 400 nm thickness deposited on silicon substrates by direct current and high-power impulse magnetron sputtering techniques. The methods of investigation of the CrN films…

Here I report a novel crystal growth phenomenon termed “radial Giant-Grain Growth” (r-GGG), which transforms spin-coated polycrystalline MAPbI3−xClx thin films into macroscopic single-nucleus domains spanning millimeters to centimeters. Although governed solely by substrate temperature and ambient humidity, r-GGG is…

Magnetic fluid shock absorbers (MFSAs) have been successfully applied in eliminating the micro-vibration of the spacecraft’s flexible structures. The method of enhancing the damping of MFSAs has always been the key issue. The tree frog’s toe pads exhibit the strong adhesion, which inspired us to learn from their…
