In the paper is presented the brief history of research conducted in Poland (at AGH University) in the area of image processing, analysis and recognition. The history is connected with changes of the technology used for problem solving. First systems are build from the separate integrated circuits of low and medium scale of integration, after this we develop some systems build on the base of VLSI elements, and now the new systems are constructed on the base of FPGA technology. Nevertheless all the time scientific group from AGH was conducted research in technological applications of vision systems. At 70th and 80th years of XX century it was pioneer works devoted to building of second in Poland and one of the first in Europe systems for computer processing of the images, now research is dedicated mainly toward real time image processing systems. © 2010 Springer-Verlag Berlin Heidelberg.

Randí et al. proposed a significant graphical representation for DNA sequences, which is very compact and avoids loss of information. In this paper, we build a fast algorithm for this graphical representation with time complexity O(n2), and find another important advantage in the representation: no degeneracy. Moreover, we propose a new method to do similarity analysis of DNA sequences based on the representation. The approach adopts four elements of covariance matrix as a descriptor, and is illustrated on the first exon of beta-globin genes from 11 different species. © 2010 IEEE.

According to the character of fiber-optic coupler, its coupling output is sensitive to the variation of coupling region's length. A new kind of coupling fiber-optic vibration sensor is presented base on this principle. The two ends of coupler are fixed onto a V-groove substrate and the coupling region is suspended in the air to realize the measurement of vibration. A prototype fiber optic vibration detection system has been successfully developed, including a sensor head, a low-cost control unit and a software package for signal processing with high resolution. The response of a simply supported beam when imposed with periodic vibration and shock is measured with fiber-optic sensor and piezoelectric sensor. The behaviors of the coupling fiber-optic vibration sensor are closely in accordance with high precision piezoelectric sensor. Experimental results indicate that the coupling fiber-optic vibration sensor has favorable vibration detection capability;it can meet the requirement of vibration measurement. ©2010 IEEE.

In order to optimize the trade-off between performance and security of digital signature in electronic commerce;an electronic seal system based on elliptical curve cryptosystem is presented. Elliptical curve cryptosystem is adopted as it is an effective system which has the advantage of fast speed and high security. The identity-based scheme is introduced to protect the system from chosen-message attack and also identifies a forged signature at the same time. The safety of the whole system is assured by public-key infrastructure techniques. Analysis and application show that the scheme proposed in the paper has the quality of high security and high efficiency of implementation. ©2010 IEEE.

This article deals with the control of mobile embedded devices via wireless transceiver. The only way how to control the mobile devices such as robots, is to use a wireless data transfer. The possible wireless transceiver solution using the nRF24L01 transceiver by Nordic Semiconductor, which works in license-free worldwide 2.4 GHz ISM frequency band, is presented. Overview of this chip is included at the beginning of this article. The main part of this article deals with the design of a communication protocol. Then some optimizations of this protocol to improve its performance and determinism are discussed. In the last part, the results of measurement of some data transfer characteristics are presented. © 2010 IEEE.

Protein remote homology detection and fold recognition are central problems in bioinformatics. In this paper, two kinds of profile-level building blocks of protein sequences, binary profiles and N-nary profiles, are presented, which contain the evolutionary information of the protein sequence frequency profile. The two building blocks are applied for protein remote homology and fold detection tasks. The latent semantic analysis (LSA) model is adopted to further improve the performance of our methods. Experiment results show that the methods based on profile-level building blocks give better results compared to related methods. ©2010 IEEE.

The chaotic suppression problem for a class of typical discrete-time hyperchaotic systems is investigated in this paper. A T-S fuzzy model-based control method is employed to eliminate hyperchaos in the considered discrete-time system. Firstly, the T-S fuzzy representation for the discrete-time hyperchaotic system is presented. Then, a state feedback controller is designed based on the parallel distributed compensation technique. According to the linear matrix inequality method and exact linearization technique, two kinds of approaches are given to solve the controller gain matrices. Finally, the validity of the proposed chaotic suppression method is illustrated by a numerical example.

A daytime and nighttime color image fusion method based on IHS transform and Multi-Wavelet transform is presented. The method can automatically merge images of a scene captured under different illumination and can be used for practical purposes. Specifically, the fused image can give more information of the context of night-time traffic videos, which makes them easier to be understood. The context is automatically captured by a camera in a fixed-position during daytime and then is fused into a nighttime image of the same scene. The advantages of this method are that it preserves the important local perceptual cues and it can avoid the problems with traditional methods such as aliasing, ghosting and haloing. © 2010 IEEE.

This paper deals with possibilities of manual control of wheeled robots. The problem is tested on a robot- soccer application. The manual computer-assisted control module creates an interface between game controller and controlled robot. There are several ways of steering implementation. The simplest is a differential steering. The module currently uses semi-automatic steering which provides a capability to move with the robot as a point. This functionality requires interaction with vision system, usage of Kahnan or similar filter and compensators. Next logical step is a fully-assisted steering. This steering system interacts with strategy and motion control module and provides additional functionality such as tracking the ball and shot. The objective is the control of many robots by only one player. © 2010 IEEE.
