Two Hand Indian Sign Language dataset for benchmarking classification models of Machine Learning 用于机器学习基准分类模型的双手印度手语数据集
Leela Surya Teja Mangamuri, Lakshay Jain, Abhishek Sharmay
Currently, a lot of research is going in the field of sign language recognition. Recognition of gesture poses a serious challenge to the system due to inconsistent illuminance and background conditions, different skin colours of the hand and each person has his/her own trait of making the gesture. It gets even more difficult with Two Hand Indian Sign Language (THISL) due to the representation of gesture with both hands. There is no proper THISL dataset available to the public. So, we present a THISL dataset consisting of 26 gestures each representing the English alphabet. This dataset consists of 50x50 images of total 9100 in which each gesture is made of 350 images and it is divided into two parts, training and test. The training set consists of 7020 images and the test set consists of 2080 images. In this paper, THISL dataset is validated on various classification models of machine learning and overall accuracy of 91.72% is achieved. This dataset serves a very good purpose for benchmarking machine learning algorithms and it is freely available to people on request to authors.
目前,在手语识别领域进行了大量的研究。由于照度和背景条件不一致,手的肤色不同,每个人都有自己的手势特征,手势识别对系统提出了严峻的挑战。使用印度双手手语(THISL)就更困难了,因为手势是用双手表示的。没有合适的THISL数据集可供公众使用。因此,我们提出了一个由26个手势组成的THISL数据集,每个手势代表英语字母表。该数据集由50x50张图像组成,共9100张,其中每个手势由350张图像组成,分为训练和测试两部分。训练集由7020张图像组成,测试集由2080张图像组成。本文对THISL数据集在各种机器学习分类模型上进行了验证,总体准确率达到了91.72%。该数据集对于机器学习算法的基准测试非常有用,并且可以免费向作者提供。

Algorithm Based on Stockwell Transform for Processing of Communication Signal to Detect Superimposed Harmonics and Transient Disturbances 基于Stockwell变换的通信信号处理中叠加谐波和瞬态干扰检测算法
Monika Mathur, Vivek Upadhyaya, Rahul Srivastava
An algorithm based on Stockwell Transform focused on processing of communication signals to detect harmonics and transient disturbances superimposed on the signals is presented in this paper. These disturbances are being superimposed on the signals in the communication channel or at the transmitter or the receiver stations. Investigated transient disturbances include impulsive transient and oscillatory transients. Communication signals incorporating harmonics or transient disturbance are decomposed with the help of Stockwell Transform and S-matrix is derived. A summation of absolute values curve, median curve and maximum absolute values plot are proposed to detect disturbances. These curves are obtained from S-matrix. On comparing these plots of signal having harmonics or transient disturbances with respective curves of pure sinusoidal communication signal, superimposed harmonics or transient disturbance have been detected successfully. Effectiveness of the proposed approach is established using the MATLAB software.

Acquiring and Analyzing Movement Detection through Image Granulation 基于图像粒化的运动检测获取与分析
Neelam Rawat, J. Sodhi, R. Tyagi
Detection of moving object is a challenging task for any video surveillance. Generally, a video surveillance consists of three levels of processing – moving object extraction, recognition and tracking – that further process for decision of the corresponding activities. As pre- and post-processing of the video might be necessary to improve the detection of moving objects, we have proposed a method that uses the coordinates of the boundary of an object with a thick white line. This paper basically shows the results through which we specify the initial search condition, the connectivity and how many pixels should be returned and the direction in which to perform the search. Further traces the exterior boundaries of objects.

Jayesh R Solanki, Divykant Meva
The world’s largest democracy has adopted electoral reforms in Assembly as well as Parliamentary elections. Electronic Voting Machine (EVM) has replaced the paper ballot system. However, there are serious concerns being raised with regards to the credibility and reliability of the EVM’s. This resulted in Voter Verified Paper Audit Trail (VVPAT) being attached to the EVM, which was found to be unverifiable and non-auditable. The primary focus of this paper is to provide a comparison between Ballot Paper Voting System and EVM highlighting the various challenges of the existing electoral system. This paper provides an insight into Block chain technology, its impact and revolution it can bring in the field of Electoral reforms in India. The comparison parameters like Time, Cost, Transparency, Risk factor, Verification/Auditing process, Authentication etc. are considered for evaluation of the different methodology discussed.

Leukemia Diagnosis using Computational Intelligence 利用计算智能诊断白血病
Sunita Chand, V. P. Vishwakarma
Leukemia is a fatal disease that is commonly found in children and also in adults above 55 years of age. It is also known as cancer of blood or bone marrow. [1] It can be categorized into myelogenous leukemia or lymphocytic on the basis of the cells affected by the disease. As the symptoms of the disease are very common like fever, fatigue and body ache, it is not easily detectable at early stages which prove fatal at later stages. So diagnosing it at early stage is crucial for the better prognosis of disease. The paper presents a comparative analysis of extensively used machine learning (ML) algorithm SVM and the relatively new ML algorithm i.e., extreme learning machine for predicting Leukemia. The classification is based on the segmentation of blood smear images publically available dataset ALL-IDB1. The results shows that ELM with an accuracy of 92.2448% outperforms SVM with accuracy 86.3636%.
白血病是一种致命的疾病,常见于儿童和55岁以上的成年人。它也被称为血癌或骨髓癌。[1]根据受累细胞的不同,可分为骨髓性白血病和淋巴细胞性白血病。由于该病的症状非常常见,如发烧、疲劳和身体疼痛,因此在早期阶段不易发现,而在后期阶段则是致命的。因此,早期诊断对疾病的预后至关重要。本文对广泛使用的机器学习算法SVM和相对较新的机器学习算法即极限学习机进行了比较分析。该分类基于对公开数据集ALL-IDB1的血液涂片图像的分割。结果表明,ELM的准确率为92.2448%,优于准确率为86.3636%的SVM。

Deepak Kumar
For the security related issues over internet two main techniques are used first is Cryptography and second is Steganography. Both are basically used for data security. Cryptography transforms the data from one form to another form while steganography hide data in an image in such a way that it cannot be detected by human eyes. This paper introduces an image steganography method using YCbCr color model based on Least Significant Bit (LSB). In this paper proposed method convert the image from RGB to YCbCr color space then secret data is hidden inside YCbCr color space using least significant bit and after hiding the data, convert it back to RGB color space. The proposed technique is evaluated by objective analysis. Different techniques of cryptography are compared using Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR). It is observed that the proposed method has high PSNR and low MSE which shows the proposed approach is very efficient to hide data in an image
对于互联网上的安全相关问题,主要使用两种技术,首先是加密技术,其次是隐写技术。两者基本上都用于数据安全。密码学将数据从一种形式转换为另一种形式,而隐写术将数据隐藏在图像中,使人眼无法检测到。介绍了一种基于最小有效位(LSB)的YCbCr颜色模型的图像隐写方法。本文提出了一种将图像从RGB颜色空间转换为YCbCr颜色空间的方法,然后利用最低有效位将秘密数据隐藏在YCbCr颜色空间中,隐藏数据后再将其转换回RGB颜色空间。通过客观分析对该技术进行了评价。使用均方误差(MSE)和峰值信噪比(PSNR)对不同的加密技术进行了比较。实验结果表明,该方法具有较高的PSNR和较低的MSE,可以有效地隐藏图像中的数据

An Improved Approach for Predicting Drug Target Interactions 预测药物靶标相互作用的改进方法
Kanica Sachdev, M. Gupta
The identification of drug protein associations assists the exploration of novel drugs, drug repurposing and drug side effect identification. The experimental evaluation of these interactions requires extensive capital and money. Thus, in-silico computational methods are being developed to aid the interaction prediction. These techniques have been broadly grouped into similarity based approaches and feature based approaches. This paper proposes a novel feature based approach to identify the probable drug protein communications. The method is based on Support Vector Machine classifier. Support Vector Machines have shown a satisfactory performance in many applications related to the pharmacology domain. To further improve the accuracy and reduce the computational complexity, dimensionality reduction by PCA has been proposed. The proposed technique achieves an AUC score of 0.822. The method has been compared to various other state of the art methods based on their respective AUC scores. The comparison has shown that the proposed approach has a better performance in contrast to the other techniques.

Defect Segmentation in Surfaces using Deep Learning 基于深度学习的曲面缺陷分割
Somit Mittal, Chahes Chopra, A. Trivedi, P. Chanak
Surface inspection is one of the most challenging tasks in the manufacturing industry. Defect classification and segmentation are the two main tasks associated with surface inspection. The major challenge lies in the collection of the dataset as it is a very costly procedure and the occurrences of defected samples are very less as compared to non defective samples. Therefore, it becomes important to devise a method that can leverage the limited data available and can also handle the class imbalance between the defected and non defected samples. In this paper, a deep learning approach is proposed that uses pertained networks to perform defect segmentation on industrial surfaces. The deep learning approach consists of an encoder and decoder architecture where on the encoder side, VGG is used with pertained imagenet weights for faster training of the model and on the decoder side, the UNet decoder model is used. The evaluation of the approach shows that the proposed method can be used for surface inspection in various industrial applications.
表面检测是制造业中最具挑战性的任务之一。缺陷分类和分割是与表面检测相关的两个主要任务。主要的挑战在于数据集的收集,因为它是一个非常昂贵的过程,并且与无缺陷样本相比,有缺陷样本的发生率非常低。因此,设计一种既能利用有限的可用数据,又能处理有缺陷样本和无缺陷样本之间的类不平衡的方法变得很重要。本文提出了一种利用相关网络对工业表面进行缺陷分割的深度学习方法。深度学习方法由编码器和解码器架构组成,其中在编码器端,VGG与相关的图像权重一起使用,以更快地训练模型,在解码器端,使用UNet解码器模型。对该方法的评价表明,该方法可用于各种工业应用中的表面检测。
