    by Sapna Gambhir, Madhumita Kathuria 
    Abstract: The vision of Wireless Body Area Network (WBAN) is to facilitate, improve, and have an immense impact on healthcare system in terms of identifying the risk level or severity factor of a patient in various emergencies. Modern and technical advances in WBAN revolutionize this area for autonomous monitoring of vital signals for a longer duration as well as from a remote place. However, handling of heterogeneous packets in a fast changing healthcare scenario has continued to be an opportunity for exploration. We present a novel concept of Dynamic Priority based Packet Handling (DPPH) which promises to add exciting capabilities to the world of WBANs. DPPH uses the principles of accurate identification and classification of heterogeneous packets to effectively determine patients critical condition and alerts the medical server. In this paper, we have focused on dynamic prioritization based queuing, scheduling, resource allocating and alerting policies for performance enhancement. The proposed approach is validated through a comparison with the existing approach. The performance of the proposed protocol is implemented using a network simulator NS-2.35 and is judged on the basis of packet delivery ratio, loss ratio, end-to-end delay, and throughput, with variation in nodes.

    Abstract: The advancements in biomedical scanning modalities such as Computed Tomography (CT), Positron Emission Tomography (PET) and Magnetic Resonance Imaging (MRI) are improving in their resolution day by day. The newly physicians may face some problem rely on exploring 2D slices and diagnosing with 3D full humans anatomy structure at the same time. In this paper, we are presenting a generalized contactless interactive Graphics Processing Unit (GPU) accelerated Compute Unified Device Architecture (CUDA) based focus and context visualization approach with displaying the inner anatomy of the large scale visible human male dataset in Multi-Coordinate Viewing System (MCVS). The focusing area has been achieved by 3D Cartesian Region of Interest (ROI). The large dataset has been structured by using Octree method. The volume rendering part has been done by using an improved ray intersection cube method for voxels with the ray casting algorithm. The final results would allow the doctors to diagnose and analyze the atlas of 8-bit CT-scan data using three dimensional visualization with the efficient frame rate rendering speed in multi-operations like zooming, rotating, dragging. The system is tested for multiple types of 3D medical datasets ranging from 10 MB to 3.15 GB.

  • Volumetric Tumor Detection Using Improved Region Grow Algorithm   Order a copy of this article
    by Shitala Prasad, Shikha Gupta 
    Abstract: This paper works on segmentation of brain pathological tissues (Tumor, Edema an Narcotic core) and visualize it in 3D for their better physiological understanding. We propose a novel approach which combines threshold and region grow algorithm for tumor detection. In this proposed system, FLAIR and T2 modalities of MRI are used due to their unique ability to detect the high and low contrast lesions with great accuracy. In this approach, first the tumor is segmented from an image which is a combination of FLAIR and T2 image using a threshold value, selected automatically based on the intensity variance of tumor and normal tissues in 3D MR images. Then the tumor part is extracted from the actual 3D MRI of brain by selecting the largest connected volume. To correctly detect tumor 26 connected neighbors are used. The method is evaluated using a publically available BRAT dataset of 80 different patients having Gliomas tumors. The accuracy in terms of detection is reached to 97.5\% which is best compared to other state-of-the-art in given time frame. The algorithm takes 4-5 minutes for generating the 3D visualization for final output.

  • Multimodality Medical Image Fusion using Nonsubsampled Rotated Wavelet Transform for Cancer Treatment   Order a copy of this article
    by Satishkumar Chavan, Abhijeet Pawar, Sanjay Talbar 
    Abstract: This paper presents nonsubsampled rotated wavelet transform (NSRWT) based feature extraction approach to multimodality medical image fusion (MMIF). The nonsubsampled rotated wavelet filters are designed to extract textural and edge features. These filters are applied on axial brain images of two modalities namely Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) to extract spectral features. These extracted features are selected using entropy-based fusion rule to form new composite spectral feature plane. Entropy-based fusion rule preserves dominant spectral features and imparts all relevant information from both the modalities to the fused image. The inverse nonsubsampled rotated wavelet transform is applied to reconstruct fused image from the composite spectral slice. The proposed algorithm is evaluated using 39 pilot image slices of 23 patients subjectively and objectively for efficient fusion. Three expert radiologists have verified the subjective quality of fused image to ascertain anatomical structures from source images. Subjective score by radiologists reveals that the fused image using proposed algorithm is superior in terms of visualization of abnormalities over other wavelet based techniques. The objective evaluation of fused images involves estimation of fusion parameters like image quality index (IQI), edge quality measure (EQa,b), mean structural similarity index measure (mSSIM), etc. The proposed algorithm presents better performance metrics over the state of the art wavelet based algorithms.

    by Arvind R. Yadav, R.S. Anand, M.L. Dewal, Sangeeta Gupta, Jayendra Kumar 
    Abstract: The texture of an image plays an important role in identification and classification of images. The hardwood species of an image contains four key elements namely, vessels (popularly known as pores in cross-section view), fibers, parenchymas and rays, useful in its identification and classification. Further, the arrangements of all these elements posses texture rich features. Thus, in this work investigation of existing texture feature extraction techniques for the classification of hardwood species have been done. The texture features are extracted from grayscale images of hardwood species to reduce the computational complexity. Further, linear support vector machine (SVM), radial basis function (RBF) kernel SVM, Random Forest (RF) and Linear discriminant analysis (LDA) have been employed as classifiers to investigate the efficacy of the texture feature extraction techniques. The classification accuracy of the existing texture descriptors has been compared. Further, Principal component analysis (PCA) and minimal-redundancy-maximal-relevance (mRMR) feature selection method is employed to select the best subset of feature vector data. The PCA reduced feature vector data of co-occurrence of adjacent local binary pattern (CoALBP24) texture feature extraction technique has attained maximum classification accuracy of 96.33

    by Sachin Negi, Yatindra Kumar, V.M. Mishra 
    Abstract: Electromyogram (EMG) signals or myoelectric signals (MES) have two prominent areas in the field of biomedical instrumentation. EMG signals are primarily used to analyse the neuromuscular diseases such as myopathy and neuropathy. In addition the EMG signal can be utilized in myoelectric control systems- where the external devices like upper limb prostheses, intelligent wheelchairs, and assistive robots can be controlled by acquiring surface EMG signals. The aim of present work is to obtain classification accuracy first by using linear discriminant analysis (LDA) classifier where principal component analysis (PCA) and uncorrelated linear discriminant analysis (ULDA) feature reduction techniques are used for upper limb prostheses control application. Next the multilayer perceptron (MLP) neural network with back propagation algorithm is used to calculate the classification accuracy for upper limb prostheses control.

  • Design of PID Controller for Magnetic Leviation System using Modified Gravitational Search Algorithm   Order a copy of this article
    by Ankush Rathore, Harish Sharma, Manisha Bhandari 
    Abstract: Gravitational Search Algorithm (GSA) is a swarm intelligence based algorithmrnwhich is inspired from the law of motion and law of gravity. GSA leads to the lossrnof the exploitation capability. To find a trade-off between exploration and exploitation capabilities of GSA, a modified gravitational search algorithm is proposed namely Exponent Inertia Weight based GSA (EIWGSA). The proposed algorithm maintains a proper balance between the exploitation and exploration skills of GSA by introducing an exponent inertia weight(EIW) parameter. The proposed algorithm is implemented over 15 benchmark functions and compared with basic GSA, BBO and PSO algorithm. Then, the MGSA algorithm is applied to design of PID controller for the magnetic leviation system over a wide difference operating air gap as 3mm, 10mm and 17mm.

  • Fast and Effective Image Retrieval using Color and Texture Features with Self Organizing Map   Order a copy of this article
    by Vibhav Prakash Singh, Ashim Gupta, Rajeev Srivastava 
    Abstract: Content based image retrieval is an emerging area in computer vision, in which we retrieve similar images from the huge set of database on the basis of their own visual content. Most of the image retrieval systems are still, incapable of providing better retrieval results in less searching time. In this paper, we introduce Self Organizing Map (SOM) clustering approach with fusion of features. Using SOM, system performances are improved by the learning and searching capability of the neural network. Here, first we extract color moment, color histogram, local binary pattern, color percentile, and wavelet transform based color and texture features. All these features are computationally light weighted, speedup the process of image indexing. Hereafter, all these features sets are fused together with equal weight. Then, these hybrid features are fed to SOM which generates clusters of images, having similar visual content. SOM produces different clusters with their centers. Further, query image content are matched with all cluster representative to find closest cluster. Finally, images are retrieved from this closest cluster using similarity measure. So, at the searching time the query image is searched only in small subset depending upon cluster size and is not compared with all the images in the database, reflects a superior response time with good retrieval performances. Experiments on benchmark database show that the proposed clustering with hybrid features performs significantly encouraging.

  • A Fireworks Algorithm for Solving Traveling Salesman Problem   Order a copy of this article
    by Zoubair Taidi, Lamia Benameur, Jihane Alami Chentoufi 
    Abstract: In this paper, a novel swarm intelligence algorithm inspired by observing fireworks explosions, called Fireworks Algorithm (FW), is proposed for solving the traveling salesman problem (TSP). The TSP is a well-known NP-hard combinatorial optimization problem. The problem is easy to state, but hard to solve. Many real-world problems can be formulated as instances of the TSP, for example, computer wiring, vehicle routing, crystallography, robot control, drilling of printed circuit boards and chronological sequencing. The proposed algorithm has been performed on TSP instances taken from TSPLIB library and has been compared with other methods in the literature. Computational results showed that the proposed firework algorithm is competitive in terms of quality of the solutions compared to other techniques.
