SAR images are affected by speckle which is a coherent process modelled as a multiplicative noise. It makes the automatic image classification difficult. Thus, many methods have been developed to remove speckle from S...

The dynamics of hybrid systems with mode dynamics of different dimensions is described. The first part explores structural properties of such multi-mode multidimensional（MD） systems. The second part considers such models under sequential switching at random times. More specifically, the backward Kolmogorov equation is derived. This is applied to a causally restricted hybrid system containing a mode with delay. Causal restriction is necessitated by the condition τ≤ 1 which must be imposed on systems with timevariant delay, τ（t）.
Information retrieval systems should provide users quick access to desired information. There are no established ways for inexperienced users to explicitly express queries for retrieving images from ecological databas...

Aimed at PSO's defect of prematurity, an improved particle swarm optimization(IPSO) is presented. The new arithmetic has better optimization performance by adding random data to premature particles' speed and position. It was applied to the parameter learning and training of Quantum Neural Network(QNN), and a higher efficiency speech recognition system which based on IPSO-QNN was established. The experimental results of MATLAB simulation showed that the new arithmetic did a better job in speech recognition rate and speed which make the best of faster quantum neural computation and PSO's global optimization ability.
This paper presents despeckling and information extraction using non-quadratic regularization. The novelty of this paper is that instead of the Gaussian prior model a Gauss-Markov random field model is chosen, because...

“Digital holography for 3D and 4D real-world objects' capture, processing, and display” (acronym “Real 3D”) is a research project funded under the Information and Communication Technologies theme of the European Commission's Seventh Framework Programme, and brings together nine participants from academia and industry (see ***). This three-year project marks the beginning a long-term effort to facilitate the entry of a new technology (digital holography) into the three-dimensional capture and display markets. Its progress at the end of year 2 is summarised.
We have proposed the voltage-current sensor of resin molded type for measurement of the power factor and harmonics. To grasp the characteristics of the conventional prototype sensor and the problem in its practical us...
