In present PSDs, the produced photocurrent flows into the dividing resistance and the bright spot position is calculated from the output currents of dividing resistance. When the existing background lights surround the target image, their photocurrent affects the image position calculation, and sensing errors are produced. We propose a new type of PSD in which the surrounding photocurrent produced by background lights can be subtracted and do not flow into the dividing resistance. The subtractions are made from individual photosensitive elements through the ideal diode which can prevent the interaction between photocurrent. In addition, for simplicity in manufacturing, a different type of PSD without the interaction prevention diode is also considered. We have performed computer simulations and it was confirmed that the proposed method would be useful. In addition, we also propose a new type of PSD which can detect the position of a black target image on light background by adopting a similar method.","PeriodicalId":263561,"journal":{"name":"Proceedings 1999 International Conference on Information Intelligence and Systems (Cat.

We propose a formalism for annotating a set of existing repositories of data (texts, audio messages, images) for a presentation planner both to reason on the deep semantic structure of the ongoing presentation and to adjust its surface form. Discourse strategies and linguistic roles coming from the field of natural language generation are exploited to ensure the assembling of coherent and cohesive messages tailored to the user's interests and needs. The aim of approach described is to develop a prototype to deliver adaptive audio based information presentations to a visitor who moves in a museum using a palmtop computer which knows where the user is.","PeriodicalId":263561,"journal":{"name":"Proceedings 1999 International Conference on Information Intelligence and Systems (Cat.

This paper will provide a brief introduction to computer viruses and hypothesise about the emergence of more intelligent targeted viruses. Existing methods of virus detection are discussed and the requirement for more intelligent detection methods is highlighted. An alternative method of detection is proposed based on the application of the CMAC algorithm in mapping the differences between redundant system components and the state of the system.

However, the order of the nonlinearity of the visual system is one of the unsolved problems in its processing. The non-Fourier motion is visually perceived motion that cannot be explained simply by the autocorrelation (Fourier motion) of the stimulus. This non-Fourier motion is said to perceive it by the pre-processing of the nonlinearity transformation in the visual system. First, we analyze the structure and the function of the nonlinear asymmetric networks in the visual system. Second, sensory integration is realized by the sensor neural networks, which consist of the forward, backward networks and the integration neuron.","PeriodicalId":263561,"journal":{"name":"Proceedings 1999 International Conference on Information Intelligence and Systems (Cat.

Regularized restoration is a method of solving ill-posed image restoration problems. Wavelet filter-banks designed upon arbitrarily sampling lattices are proposed in order to replace the conventional regularization operator. A regularization parameter corresponds to each decomposition channel of the wavelet filter-bank. The proposed model estimates regularization parameters iteratively. The current estimate of the restored image is used in such an estimation. The model assumes that the degradation may be represented by a perfect reconstruction filter bank. Factorizations of unitary matrices using Givens rotations allow for efficient representations of a variety of degradations. Should both the degradation and the smoothing filter be decomposed by wavelet filter banks, the restoration problem may be split into independent restoration problems in each transformation channel. Regularization parameters are evaluated iteratively in each channel. Numerical results indicate better (improvement in signal-to-noise-ratio) figures conventional iterative regularization methods.","PeriodicalId":263561,"journal":{"name":"Proceedings 1999 International Conference on Information Intelligence and Systems (Cat.

FSMIQ: fuzzy similarity matching for image queries FSMIQ:图像查询的模糊相似性匹配

FSMIQ uses shape and color information to generate a 2630 byte long information vector that describes the shape and color distribution in the image. This information is generated by the application of the discrete wavelet transform to the YIQ color space and picking the appropriate information by quantization of the Y channel coefficients and using fuzzy linguistic variables for color description. The information vectors that correspond to the images in a given database are used for the queries. Queries are carried out using the generalized Tversky index, a similarity index that is based on human similarity perception, which has been developed by the authors. Different retrieval results are calculated for shape and color; a final data fusion process takes place to provide the overall results. For examining the efficiency of FSMIQ, we use the AVRR and IAVRR metrics proposed by Flickner et al. (1995). Our experiments indicate very good performance, both visually and based on the aforementioned metrics.","PeriodicalId":263561,"journal":{"name":"Proceedings 1999 International Conference on Information Intelligence and Systems (Cat.

Furthermore, all these capabilities must be integrated into a single and complete autonomous system.

Retriever utilizes existing search engines to obtain the starting points for its subsequent autonomous exploration of the Web. Then it conducts a self-training process in order to learn the query domain and to increase its efficiency. When the query domain is learned, the agent expands the original query, reforms its search strategy and goes out looking for the documents to be presented to the user.
