The Local Binary Pattern (LBP) operator and its variants play an important role as the image feature extractor in the textural image retrieval and classification. The LBP-based operator extracts the textural information of an image by considering the neighboring pixel values. However, the LBP-based feature is not a good candidate in capturing the color information of an image, making it is less suitable for measuring the similarity of color images with rich color information. This work overcomes this problem by adding an additional color feature, namely Color Histogram Feature (CHF), along with the LBP-based feature in the image retrieval domain. Experimental result shows that the hybrid CHF and LBP-based feature presents a promising result and outperforms the existing methods over several image databases.

Since Software-Defined Networking (SDN) technologies have been commonly used in networking components for designing Future Internet, the fault tolerance design becomes a fundamental requirement in network deployment. This paper presents a prototype of path switching method based on OpenFlow protocol. In contrast of the traditional network architecture, this implementation provides an adaptive path switching method when link failure is detected, which reducing the time of interruption.

In this paper, a back lighting color image enhancement method using color saturation and image fusion is presented. First, the saturation component of color image is computed by using HSV or HSI color space. Then, two different exposed images are generated by using weighting function method. Next, the enhanced image is obtained by fusing input color image and two different exposed images. Finally, several numerical examples are demonstrated to show the effectiveness of the proposed enhancement method.

Low crest factor (CF) multi-sine can bring high signal-to-noise ratio for fast frequency response function (FRF) measurement. This paper synthesizes a broadband multi-sine signal which has 15 flat and quasi-logarithmically spaced spectrum and a low CF of 1.8484. The multi-sine is realized based on a field-programmable gate array (FPGA). The generated multi-sine has the fundamental frequency of 8 kHz, and spans logarithmically from 8 kHz to 800 kHz at its 15 harmonic components. This paper provides an applicable solution to synthesize and generate broadband multi-sine signals.

The KNN algorithm has a significant effect on classification prediction in Data Mining. In order to solve the drawbacks for KNN algorithm to reduce the costs of the calculation and increase the accuracy, this paper proposed a prototype generation method with same class label proportion for classification to ensure that each class has at least a prototype to be represented. We compare the average success rate of GA, PSO, DE and proposed method SPDE. The experimental results show that the SPDE has more opportunity to do better than others in those problems.

The DPWM device is an important component in many industrial applications, such as motors, robots, DC/DC converters, and so on. However, the counter-based DPWM intends to extend its resolution, and thus the higher clock frequency is required. In this paper, by a cyclic self-trigger of monostable multivibrator, the proposed DPWM device can extend its resolution without increasing the reference clock frequency. Moreover, it also maintains as low hardware complexity as the conventional counter-based DPWM.

This paper demonstrates a high performance brain-computer interface (BCI) that allows users to dial phone numbers. The system is based on Canonical Correlation Analysis (CCA) and Steady-State Visual Evoked Potential (SSVEP). Through six buttons (9Hz, 10Hz, 11Hz, 12Hz, 13 Hz, 14Hz) displayed on the screen, subjects can choose the number by gazing at the computer interface. This proposed EEG (Electroencephalography) system has been implemented in Field-Programmable Gate Arrays (FPGA) and it features high accuracy, integration density, and low cost. These features are meaningful for implementing a real time SSVEP-based BCI.

In this paper, the proposed algorithm based on Hilbert-Huang Transform (HHT) is used to analyze the photoplethysmography (PPG) signal. In fact, PPG is nonlinear and nonstationary signal which is suitable for HHT method to achieve the capability of precise decomposition. The time series data are decomposed into Intrinsic Mode Function (IMF) with Ensemble Empirical Mode Decomposition (EEMD) algorithm. This study proposed a novel instantaneous pulse rate variability (iPRV) measurement based on EEMD method to analyze the very high frequency band (0.4-0.9Hz) of IMF5 which contains heart rhythm component.
