This investigation deals with the design method of a static output feedback controller for continuous-time T-S fuzzy systems via iterative linear matrix inequalities. First, a matrix inequality that guarantees the stability of the nonlinear system is introduced. Based on this, an algorithm for finding the stabilization control gains, using the cone complementary linearization method, for continuous-time T-S fuzzy systems is presented. The validity of the proposed algorithm is verified through a simple example. © ICROS 2021.

As the better high quality image is required for digital image scaling, longer processing time is required so the technology that can make the high quality image quickly is needed. We propose the double linear-cubic convolution interpolation creating the high quality image with low complexity. When compared to peak signal-to-noise ratio(PSNR) and computation time, the proposed interpolation provided better PSNR and low complexity than bicubic convolution interpolation. Copyright 2014 ACM.

Pulsed eddy current (PEC) technique is attractive for detection of surface defects and wall-thinning in covered electrically conductive materials. This paper discusses development of PEC technique and two different types of self-nulling probes (differential Hall sensors and Double-D differential coils) for detection of surface notches in a thick stainless steel plate. PEC testing of covered objects is attempted. In this regard, the influence of lift-off on the PEC signal due to insulation shims and thin aluminum layer is studied using the peak amplitude and the performance of the two probes is compared. The results showed that the PEC instrument, probes and scanner developed can be used for detection as well as imaging of defects in stainless steel plates covered with insulation. © 2014 The authors and IOS Press.

This paper presents a three-dimensional (3D) motion analysis, motion database construction, and 3D motion visualization of national rider athletes under horse simulator environments. The 3D motion database captured from national rider athletes are constructed by four riding types such as walking, trotting, cantering, and galloping. Finally we cover the motion analysis and evaluation based on the flexion angle of elbow, knee, and backbone, the y-axis position of hip by each riding type for 3D motion analysis of national rider athletes in horse simulator. © 2013 IEEE.

In this paper, PCA-based long distance face recognition algorithm applicable to the environment of intelligent video surveillance system is proposed. While the existing face recognition algorithm uses the short distance images for training images, the proposed algorithm uses face images by distance extracted from 1m to 5m for training images. Face images by distance, which are used for training images and test images, are normalized through bilinear interpolation. The proposed algorithm has improved face recognition performance by 4.8% in short distance and 16.5% in long distance so it is applicable to the intelligent video surveillance system. © 2013 Springer-Verlag.

Recently as the incidences of terrorism and crime increase, the utilization of video surveillance system such as CCTV is increased. The increase of video surveillance system is useful in maintaining the safety of people's living and public order, however, the issue has been brought up about privacy invasion. For this, researches on the masking method to protect the privacy are being carried out. The masking method can protect privacy by eliminating the visual information but reduces the surveillance function. Therefore, the techniques that satisfy the human identification-based privacy protection and surveillance function at the same time have been researched. In this paper, the human identification method that is applicable to the existing privacy protection method and video surveillance system is explained. © 2011 IEEE.

Recently, the use of security surveillance system including CCTV is increasing due to the increase of terrors and crimes. However as the data recorded through the video surveillance system is exposed, the invasion of privacy is raised. The studies on the technology of protecting privacy from the surveillance system in addition to these organizations are actively carried out. To distinguish the human of privacy protection, the identification technique is necessary. This paper proposes the human identification method that uses height and clothing-color information appropriate for the intelligent video surveillance system based on smartcard. It can obtain reliable feature information using smartcard. In this paper, representative colors are extracted by applying octree-based color quantization technique to the clothing region and height is extracted from the geometrical information of the images. Identification is accomplished by comparing the similarities between two data based on Euclidean distance. From the experiment, we could see that the identification of a human can be checked through the proposed system. © 2010 IEEE.

In this paper, we propose an incremental method of Granular Networks (GN) to construct conceptual and computational platform of Granular Computing (GrC). The essence of this network is to describe the associations between information granules including fuzzy sets formed both in the input and output spaces. The context within which such relationships are being formed is established by the system developer. Here information granules are built using Contextdriven Fuzzy Clustering (CFC). This clustering develops clusters by preserving the homogeneity of the clustered patterns associated with the input and output space. The experimental results on well-known software module of Medical Imaging System (MIS) revealed that the incremental granular network showed a good performance in comparison to other previous literature.

The research on the technology of protecting privacy from the surveillance system in addition to these organizations is actively carried out. At this time, to distinguish the human of privacy protection, the identification technique is necessary. For identification, the proposed system uses soft-biometrics such as color and height information based on smartcard. It can obtain reliable feature information using smartcard. In this paper, representative colors are extracted by applying octree-based color quantization technique to the clothing region and height is extracted from the geometrical information of the images. The identification is accomplished by comparing the similarities between two data based on Euclidean distance. Through identification by using multiple information rather than single information, the proposed system demonstrates the possibility of human identification under the surveillance camera environment. © 2010 IEEE.

To optimize the energy consumption during transmission in a secure remote fingerprint authentication system, most approaches have considered a fixed-rate compression of WSQ(Wavelet Scalar Quantization). To balance the energy consumption and the recognition accuracy, however, we need to consider the total energy consumption during compression/encryption/transmission and the quality of the given image. In this paper, we first develop an energy-accuracy prediction model. Then, from the given image, we can evaluate the quality of it. Finally, from the user's minimum requirement of the recognition accuracy, the energy-optimized compression rate under the requirement can be derived adaptively. Based on the experimental result, we show that total energy consumption of the fixed approach can be reduced by 29%. ©2010 IEEE.
