Textural filters based on the texture spectrum
Pattern Recognition, 1991Abstract Conventional digital filtering techniques, based on classical Fourier analysis (that is, low-pass, high-pass and band-pass), are widely used in digital image processing. Unsatisfaction may be encountered when applying these filters to texture analysis of images, where one needs some specific spatial filters which are able to transform an ...

Current shape-from-shading and shape-from-texture methods are applicable only to smooth surfaces, while real surfaces are often rough and crumpled. To extend such methods to real surfaces we must have a model that also applies to rough surfaces. The fractal surface model provides a formalism that is competent to describe such natural 3-D surfaces and ...

Texture features based on texture spectrum
Pattern Recognition, 1991Abstract Texture is an important spatial feature useful for identifying objects or regions of interest in an image. This paper presents a new set of textural measures derived from the texture spectrum. The proposed features extract textural information of an image with a more complete respect of texture characteristics (in all the eight directions ...

We characterize ``visual textures'' as realizations of a stationary, ergodic, Markovian process, and propose using its approximate minimal sufficient statistics for compressing texture images. We propose inference algorithms for estimating the ``state'' of such process and its ``variability''. These represent the encoding stage.

Compact color–texture description for texture classification
Pattern Recognition Letters, 2015We show that combining multiple texture description methods significantly improves the performance compared to using the single best texture method alone.We further propose to use information theoretic compression approach to compress high-dimensional multi-texture features into a compact heterogeneous texture representation.We perform a comprehensive ...

We present for creating texture over an surface mesh using an example 2D texture. The approach is to identify interesting regions (texture patches) in the 2D example, and to repeatedly paste them onto the surface until it is completely covered. We call such a collection of overlapping patches a lapped texture.

Crucial to accounts of complexity is the history of the concept of emergence. Pride of place is generally given to G. E. Lewes, who in 1879 offered a theory of "emergents," of the unpredictable and incommensurate effects which follow from the crossing of causes.

Abstract Shear and compression strengths of individual carrots were measured with the Instron Universal Testing Machine. Compression correlated highly, but shear poorly, with sensory hardness as judged by compressing and flexing. The study confirmed the usefullness of the coefficient of compression in predicting textural quality of carrots.

We present metamaterial textures---3D printed surface geometries that can perform a controlled transition between two or more textures. Metamaterial textures are integrated into 3D printed objects and allow designing how the object interacts with the environment and the user's tactile sense.
