The role of local grouping and global orientation contrast in perception of orientation-modulated textures
We explored the contribution to perception of orientation-modulated textures of visual processes selective either for orientation contrast or orientation grouping. To distinguish between these two processes we manipulated the axis of local grouping of texture elements independently of the direction of global orientation modulation. The general question posed was whether visibility of texture st...
متن کاملTextures and Wavelet-Domain Joint Statistics
This paper presents an empirical study of the joint wavelet statistics for textures and other random imagery. There is a growing realization that modeling wavelet coefficients as independent, or at best correlated only across scales, assuming independence within a scale, may be a poor assumption. While recent developments in wavelet-domain Hidden Markov Models (notably HMT-3S) account for withi...
متن کاملAlignment of orientation-modulated textures
We conducted a Vernier acuity experiment using orientation-modulated (OM) textures in which the overall shape (skewness) of the modulations was manipulated independently of their orientation content. Misalignments between OMs were consistent with the application of global positional tags, but not on the basis of a single cue (e.g. centroid, peak, or zero-crossing). Instead, modelling of our res...
متن کاملParametric Texture Model based on Joint Statistics
Texture images are a special class of images that are spatially homogeneous and consist of repeated elements, often subject some randomization in their location, size, color, orientation, etc. Textures can be classified into different classes or groups based on their structure and origin. Figure 1 gives some example textures. Textures are widely used in varied fields ranging from bio medical im...
متن کاملStatistics of Natural Stochastic Textures ∗
Statistics of natural images have become an important subject of research in recent years. The highly kurtotic, non-Gaussian, statistics known to be characteristic of many natural images are exploited in various image processing tasks. We focus on Natural Stochastic Textures (NST), an important subset of natural images. In the first part of this report, we show their abundance in natural images...
