We know that an audio speech signal can be unambiguously decoded by any native speaker of the language it is uttered in, provided that it meets some quality conditions. But we do not know if this is the case with visual speech, because the process of lipreading is rather mysterious and seems to rely heavily on the use of context and non-speech cues. How much information about the speech content...

Visual Process Patterns (VPP) is a visual language to describe constraints on the behavior of UML Activities. They have been developed for the sake of formulating and verifying requirements on business process models in a visual, intuitive way (with UML Activities being one possible description language). In the VPP approach, a visual process pattern is translated into an LTL formula, which can...

(1) In a previous paper(1) a statistical theory of visual thresholds was reported which accounts for the influence both of quantum noise and of visual noise added to the test patterns. This theory finds particular application in the pre­ diction of thresholds of vision through image intensifying systems which superimpose system noise on the observed scenes. In a subsequent paper(2) an additiona...

Visual patterns represent the discernible regularity in the visual world. They capture the essential nature of visual objects or scenes. Understanding and modeling visual patterns is a fundamental problem in visual recognition that has wide ranging applications. In this paper, we study the problem of visual pattern mining and propose a novel deep neural network architecture called PatternNet fo...

  Introduction: The term dynamic assessment (DA) refers to an assessment, by an active teaching process, of a child's perception, learning, thinking, and problem solving. The process is aimed at modifying an individual's cognitive functioning and observing subsequent changes in learning and problem-solving patterns within the testing situation. DA has been advocated as an alternative and/or sup...

Background: The major limitation in human vision is refractive error. Auxiliary equipment and methods for these people are not always available. In addition, limited range of accommodation in adult people when switching from a far point to a near point is not simply possible. In this paper, we are looking for solutions to use the facilities of digital image processing and displaying to improve ...
