the process that forms during writing is under an important principle and according to abstract form of alphabet and their composition. this principle is called writing system. therefore, writing is accounted an artistic work. cognitive it is important in different dimension view, because of man abstract view point that has led emergence of communication system. this paper for cognitive analysi...

objective: deficits in the processing of facial emotions have been reported extensively in patients with schizophrenia. to explore whether restricted attention is the cause of impaired emotion processing in these patients, we examined visual attention through tracking eye movements in response to emotional and neutral face stimuli in a group of patients with schizophrenia and healthy individual...

Face to face dialogue is the most natural mode of communication between humans. The combination of human visual perception of expression and perception in changes in intonation provides semantic information that communicates idea, feelings and concepts. The realistic modelling of speech movements, through automatic facial animation, and maintaining audio-visual coherence is still a challenge in...

We describe progress towards visual analysis of pedestrian motion. While trajectories of humans on foot are stochastic in nature, in a constrianed situation underlying patterns of motion can be identified. The work presented in this report focuses on movement of people through scenes which are under visual surveillance. In this case, analysis of continuous video footage provides a history of ma...

Many problems in the fields of Computer Vision deal with image data that is embedded in very high-dimensional spaces. However, it is typical that there are few variables, with a small number of degrees of freedom, that control the underlying process that generated the images. Therefore, a typical assumption behind many algorithms is that the data lie on a low-dimensional manifold. Modeling the ...

Visual analytics that combine analytical techniques with advanced visualization features is fast becoming a standard tool in extracting information from complex data. A number of sophisticated tools have been developed for this purpose, which necessitates formal methods to guide the creation of such tools and also compare them. Further, there is a need for visual analysts to document the steps ...

We present the DEVise toolkit designed for visual exploration of stream data. Data of this type are collected continuously from sources such as remote sensors, program traces, and the stock market. A typical application involves looking for correlations, which may not be precisely deened, by experimenting with graphical representations. This includes selectively comparing data from multiple sou...

The quality, certainty, or confidence of decisions made during the visual analytics process depends on many factors, including the completeness and reliability of the initial data, information loss due to filtering, sampling, and other transformations, and the accuracy and clarity of the visual presentation. Unfortunately, in most visualization tools the analyst is unaware of these and other fo...
