Texture segregation in chromatic element-arrangement patterns.
An element-arrangement pattern is composed of two types of elements arranged differently in different regions of a pattern. Rapid texture segregation depends on spontaneously discriminating the difference in the arrangement of the elements. Five experiments investigated the perceived segregation of patterns composed of two types of squares arranged in vertical stripes in the top and bottom regi...

Patterns in Iranian art should be called message painting and expression painting, which sometimes manifests itself directly and sometimes in symbolic language. One of the places of expression and emergence of symbols in Iran is the "carpet". In addition to the traditional and local aspects, these patterns and expressions can express the creative mind influenced by the environment around the ca...
متن کاملThe Spatial Limit for Motion Detection in Noise Depends on Element Size, not on Spatial Frequency
When a random spatial noise pattern is displaced for a short distance it seems to move coherently, but when the displacement exceeds a certain value, the direction of motion cannot be clearly perceived. We measured the displacement limit (Dmax) for a two-frame sequence and found that it depended on the size of the elements comprising the random pattern, even when low spatial frequencies were re...
متن کاملpatterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
15 صفحه اولSimple Shape Detection Using Pattern Spectrum
Pattern spectrum is a shape size descriptor of an object content of a digital image. It is a technique for extracting various shape and resolution information of a digital image. Basic features of Pattern Spectrum (PS) allow us to detect simple predefined shapes of a digital image what can be used in different tasks of intelligent terminal system. A discussion of the basic ideas of pattern spec...
