Abstract

As wireless sensor networks continue to grow in usage for distinct applications. Storage (memory) requirement and security are major problems for these resource limited networks. This paper present a novel and an efficient key establishment and management scheme for WSNs, named Random Initial and Master Key (RIMK).We showed that our proposed technique, manages keys randomly with less storage (i.e. only two keys), less communication and computation overhead compared to existing Localized Encryption and Authentication Protocol (LEAP), in which every node uses four different  keys in a static pattern and occupy greater storage space, which increases overhead and complexity in the network. Simulation results show that RIMK is more efficient and robust than LEAP. DOI: http://dx.doi.org/10.11591/telkomnika.v11i6.2703

Abstract

Way of walking is a spatio-temporal phenomenon that typifies the motion characteristics of human. In this paper, we propose a human gender identification method based on the outdoor surveillance of human gait using statistical techniques and geometrical function applied to three-dimensional (3D) joint movement data. The statistical techniques are used to define the features of the joint of the human gait, and the geometrical function applied for gender recognition. Our proposed scheme is based on extraction of the concern joint (hip joint) data that provides plentiful information for gender recognition. Here the rotation angle data of a hip joint were computed from the Biovision Hierarchical data (BVH file). The use of BVH file for human gender recognition is a novel feature of our work. The results indicated that the proposed approach is highly reliable for gender recognition. DOI: http://dx.doi.org/10.11591/telkomnika.v11i6.2274

Abstract

Aiming at the defects and shortages of traditional moving vehicles detection algorithms, by the analysis and comparison of the existing detection algorithms, we propose an algorithm that combined with frames with symmetric difference and background difference to detect moving vehicle in this paper. First, two different difference images by using frames with symmetric difference and background difference are gained respectively and two binary images can be gained by the appropriate threshold, then the contour of moving vehicles can be extracted by applying OR operation in the two binary images. Finally, the precise moving vehicles will be gained by mathematic morphological methods. In this paper we use Harris operator, Feature Points such as edges and corners are extracted, followed by block-matching to track the Feature Points in successive viedo frames. Many vehicles can be tracked at the same time automatically since  the  information is obtained from video sequences. DOI: http://dx.doi.org/10.11591/telkomnika.v11i6.2613

Abstract

An efficient digital watermark embedding algorithm for color image was presented in this paper, which is based on the discrete wavelet transform (DWT) and the spectral characteristics of human vision system. Firstly, three color separations was performed for color image, and color components of color image were transformed by DWT. Secondly, the embedding position of the watermark was confirmed by comparing the energy value of the low frequency sub-band in the transformed blue component and green component. Thirdly, the watermark was made Arnold Transform for encryption and was embedded in the color component with a larger power. Finally, this paper made the simulation experiments to evaluate the performance of the watermark. The simulation results showed that the embedded watermark had good invisibility and robustness for the common image processing, such as filtering, noise, especially compression and cropping. DOI: http://dx.doi.org/10.11591/telkomnika.v11i6.2681

Abstract

To overcome the shortcomings such as significantly de-noising effect and easily losing the details of the image characteristics of the existing image de-noising methods, an image de-noising algorithm based on the hybrid wavelet transform was proposed. The algorithm integrated the advantages of wavelet de-noising retaining image details features and Wiener filter obtaining the optimal solution, and took the images processed by wavelet transform and Wiener filter as male and female of the initial population. The steps of the algorithm are as follows: mapping from image space to coding space, iterating to parents through selection, crossover and mutation operation until the offspring meeting the constraints was obtained, reducing the superior offspring to image space, gaining the approximate optimal solution. Theoretical analyses were made on the core of the algorithm, coding, crossover and mutation. The algorithm was applied to agricultural machinery parts image de-noising such as plough and disk harrow. The results showed that it had the advantages of high peak signal to noise ratio (PSNR), obvious edge characteristics, good vision effect, and so on. The result of the present work implied that the proposed algorithm is an effective and feasible exploration. DOI: http://dx.doi.org/10.11591/telkomnika.v11i6.2723

Abstract

Feature extraction is one of key technologies of the palmprint identification. In the light of the characteristics subspace palmprint identification technology, the two-dimensional principal component analysis, two-dimensional fisher linear discriminant and two-way two-dimensional principal component analysis algorithm is deeply analyzed. Based on two-dimensional subspace palmprint identification algorithm is a direct projection of the palmprint image matrix and is achieved very good results for dimension reduction. This paper proposed a mixed two-dimensional linear discriminant dimension reduction algorithm which can eliminate the relevance of rows and columns to get the best projection vector and extract optimal discriminant information. Experimental results show that the proposed method has faster extraction speed, higher recognition rate and better robustness. DOI: http://dx.doi.org/10.11591/telkomnika.v11i6.2608

Abstract

Various campaigns such as ‘Save the Earth’, ‘Earth Hour’, and ‘Reduce, Reuse, Recycle’ are held to create environmental awareness among the general public. The effort is seen endlessly using any means of presentation and communication medium in order to ensure the intended message reach its audience. Meanwhile, the availability of mobile devices and the advent of natural user interfaces have simplified the interaction in games so that it is intuitive for vast audience at different abilities. Hence, this would possibly provide wider audience an engaging experience while playing games and at the same time absorbing the intended message. This article describes the process of designing and developing a go-green tridimensional (3D) game on a mobile platform. It also discusses educational benefits of games and how the concept of environmental awareness is integrated into the game play in order to educate the general public especially the young ones about their social roles. Initial results on performance assessment reveal that the functionality of interactive elements in the game is excellent and young ones did not have difficulties in playing the game. Future work will focus on how 3D mobile games facilitate informal learning process such as inculcating environmental awareness to the general public. DOI: http://dx.doi.org/10.11591/telkomnika.v11i6.2657

Abstract

Distributed Generation (DG) generates electricity from many small distributed energy sources or even customer’s small power plants. It always comes up with the terminal customer power quality management and the technology of energy cascade utilization. DG has lots of characteristics such as one single point of access, being power and being load, two operating mode in a grid or as an island, a great deal of application of power electronic devices, easily influenced by natural environmental factors etc. DG has impacts to the original grid in terms of the grid structure, the direction of power flow, the fault current level when a fault happens, etc and subsequently the relay protection mechanism must be looked into. This paper analyses the impact of accessing the DG on the distributed grid in three cases which are the DG accessing to the end of the distributed feeders, to the middle, and the DG accessing to lines, on relay protections. At the end of the paper it also comes up with improvements in detail. DOI: http://dx.doi.org/10.11591/telkomnika.v11i6.2674
