Authors: Ding Wei Li , Jiang Feng , Yan Jia Qing
Published: June 2011

Magnetic Resonance Imaging (MRI) has been widely used in clinical diagnose. Segmentation of these images obtained by MRI is a necessary procedure in medical image processing. In this paper, an improved level set algorithm was proposed to optimize the segmentation of MRI image sequences based on article [1]. Firstly, we add an area term and the edge indicator function to the total energy function for single image segmentation. Secondly, we presented a new method which uses the circumscribed polygon of the previous segmentation result as the initial contour of the next image to achieve automatic segmentation of image sequences. The algorithm was tested on MRI image sequences provided by Chuiyanliu Hospital, Chaoyang District of Beijing; the results have indicated that the proposed algorithm can effectively enhance the segmentation speed and quality of MRI sequences.

Published: June 2011

In the facial expression recognition, a dimension disaster will arise when taking the coefficient of Gabor transforms as the expression eigenvectors. To avoid this issue we draw grids on facial region, making the mean coefficient value of Gabor transforms of each gird as the eigenvectors. Furthermore we classify the expression by constructing the multi-class C-SVC, improved the accuracy and speed of the algorithm by dropping the redundant features using sequential backward selection. The experimental result proves the superiority of the algorithm we proposed to other algorithms.

Published: June 2011

Local image representation based natural image classification is an important task. SIFT descriptors and bag-of-visterm (BOV)method have achieved very good results. Many studies focused on improving the representation of the image, and then use the support vector machine to classify and identify the image category. However, due to support vector machine its own characteristics, it shows inflexible and slower convergence rate for large samples，with the selection of parameters influencing the results for the algorithm very much. Therefore, this paper will use the improved support vector machine algorithm be based on ant colony algorithm in classification step. The method adopt dense SIFT descriptors to describe image features and then use two levels BOV method to obtain the image representation. In recognition step, we use the support vector machine as a classifier but ant colony optimization method is used to selects kernel function parameter and soft margin constant C penalty parameter. Experiment results show that this solution determined the parameter automatically without trial and error and improved performance on natural image classification tasks.

A novel method combing feature constraint with multilevel strategy to improve simultaneously the registration accuracy and speed is proposed for non-parametric image registrations. To images between which the local difference is large, integrating feature constraint constructed with local structure information of images into objective function of image registration improves the registration accuracy. When applying feature constraint under multilevel strategy, parameter searching is prevented from entrapped into local extremum by using the optimization result on coarser levels as the starting points on finer levels; meanwhile traditional optimization methods without demanding intelligent optimization algorithms which consume more time can find the accurate registration parameter on finer levels, so registration speed is improved. Experimental results indicate that this method can finish fast and accurate registration for images between which there exists large local difference.

Published: June 2011

Importance measures are widely used to characterize the contribution of components to the system performance such as reliability, availability, risk, etc, and thus give great help in identifying system weaknesses and prioritizing system improvement activities. Although much work has been carried out on component importance analysis, most studies only concern the consistent states of components within which components exhibit consistent performance until state changes happen. Unfortunately, field data shows that many transient faults in components may result in severe consequences without causing any state changes, and, this can lead to a misunderstanding of component importance. This paper focuses on the reliability importance analysis in presence of transient faults, and proposes a composite measure for evaluation. A sample series parallel system is analyzed to illustrate the use of this measure.

Published: June 2011

A highly efficient, single-port SRAM-based loop filter based on H.264 is presented. Hybrid edge filtering order, efficient memory organization for both on-chip SRAM and transposition buffers, and five-stage pipeline architect are adopted in the design. Efficient transposition buffer organization reduces the gate counts and the memory access times. By using hybrid edge filtering order and alternating output memory update scenario, zero stall cycle in pipeline flow is realized. To balance on-chip memory size and bus bandwidth, the design can be configured to operate in on-chip memory and off-chip memory modes.

Published: June 2011

In this paper, we present a novel method for designing a controller with good rubustness for variable-speed wind energy conversion systems based on a characteristic model. Due to the stochastic operating conditions and the inevitable nonlinear characteristics inherent in the system, the dynamic model is usually too complex for the system analysis and controller design. Therefore, we first develop a detailed plant characteristic model of a variable-speed wind energy conversion system, which simplifies significantly the engineering implementation. Then the sliding mode incorporating fuzzy tuning schemes is applied to design a controller that optimizes the converter system efficiency and robustness. Analysis and experimentation show that the method achieves satisfactory wind energy tracking.

A New Wood Recognition Method Based on Texture Analysis
Authors: Sun Ling Jun , Ji Zhi Wei , Wang Hang Jun
Published: June 2011

A novel and efficient wood recognition method based on texture analysis is presented in this paper. Firstly, the sample images are divided into several regions after cutting from wood stereogram images. Then, more features are extracted by Gabor Wavelets through five scales and eight orientations. For getting the key points of these Gabor features, clustering and sifting operation are used to dislodge the dimmed features that extracted from the noise regions, such as cleavage region, resin canal region and so on. Finally, the Earth Mover’s Distance is used as the distance measure to compare these features by nearest neighbor classifier. The experiment on 24 species and 480 sample images shows that the recognition rate can even up to 97.5 percents, which gives a satisfactory classiﬁcation performance compared with the current state-of-the-art methods.
Restaurant Facilities Layout - Reducing Carbon Footprint Aspect
Authors: Ho Zih Ping
Published: June 2011

Reducing carbon footprint is a trend within modern green restaurants. A carbon footprint is the total set of greenhouse gas (GHG) emissions caused by an organization, event or product. Food and beverage restaurants have to deliver food using a minimal carbon footprint. Of previous researches, only a small fraction is focused on reducing carbon footprints in a culinary room. Besides, a carbon footprint cost model was hard to solve in economic computation time. Therefore, the main purpose of this research is through a distributed information system to accelerate computing ability of a carbon footprint cost model. Through the distributed computing, our experimental results showed that the proposed approach outperformed the literature approach efficiently. The algorithm improved rate was 68.6%, and low down 82.1% carbon footprint than manual. The proposed approach could contribute to accelerate calculations in others problems due to using multiple machines in future researches.
