End-stopped perceptive fields associated with line targets were demonstrated previously with length and width Westheimer functions. In this study we investigated rectifying non-linearity in these perceptive fields to examine whether they directly reflect the organization of cortical receptive fields. Specifically, we reversed the polarity of parts of the background field associated with a speci...

This work addresses the problem of document image analysis, and more particularly the topic of document structure recognition in old, damaged and handwritten document. The goal of this paper is to present the interest of the human perceptive vision for document analysis. We focus on two aspects of the model of perceptive vision: the perceptive cycle and the visual attention. We present the key ...

This paper is a sequel to Kurano et al [9], [10], in which the fuzzy perceptive models for optimal stopping or discounted Markov decision process are proposed and the methods of computing the corresponding fuzzy perceptive values are given. Here, we deal with the average case for Markov decisin processes with fuzzy perceptive transition matrices and characterize the optimal average expected rew...

together, people have used them for communication. From email—one of the first network applications—to the original MIT Zephyr notification system to the now-popular AOL Instant Messenger System, people use computers to break down physical distances and provide a sense of awareness about another person in another place. Beyond basic text interaction, research—such as the Portholes project at Xe...
