In this paper, the effect of low, middle and high frequency DCT coefficients are investigated onto gray scale image watermarking in terms of imperceptibility and robustness. The performance of Lagrangian twin support vector regression (LTSVR), which was successfully applied on synthetic datasets obtained from UCI repository for various kinds of regression problems by Balasundaram et al. [9], onto image watermarking problem, is validated by embedding and extracting the watermark on different standard and real world images. Also the good learning capability of image characteristics provides the good imperceptibility of the watermark and robustness against several kinds of image processing attacks verifies the high generalization performance of LTSVR. Through the experimental results, it is observed that significant amount of imperceptibility and robustness is achieved using low frequency (LF) DCT coefficients as compared to middle frequency (MF) and high frequency (HF) DCT coefficients as well as state-of-art technique. © 2015 IEEE.

作者： Akanksha Upadhyaya Vinod Shokeen Garima Srivastava Amity Institute of Information Technology Amity School of Engineering Computer Science Amity University WUST Shandong India

During data transmission, data can be transmitted in the form of text, image, audio and video, hence securing all kinds of data is most essential in today's era. Securing Image data is one of the major concern and a complex term. Various visual cryptographic techniques have been developed for confidentiality, authenticity and integrity of images during transmission and when it is received at other end. This paper proposes an Image encryption technique on the basis of 128-bit AES, Feature extraction and random no. generation. Applying AES in two levels and generating key on the basis of feature extraction makes the system more confidential and secure against cryptanalysis attacks.

This paper presents the experimentation done in order to flourish a low price and impressionable information system to provide useful information to farmers in a timely manner so as to assist their decision making process. The primary reason behind development of this system was to automate the flow of information to farmers since agriculture is the backbone of our country. Gram Sandesh Transmission is a web disciplined system which targets all sort of audience by means of its ios application (for iphone users),android application(for android users), messaging server(for basic mobile handset) and gsm based led boards (for those who don't owe a mobile handset). Farmers are provided with weather related information on daily basis so that necessary decision regarding sowing of seeds, weeding, harvesting, irrigation could be taken. The system warns with any disaster related information so that necessary steps could be taken. Another module of the system deals with providing “Sarkari Mandi Bhaav” (Govt. Market Price) and thus reduces the chances of fraud prices quoted by middleman to farmers.

Among the emerging technologies in the nanotechnology domain Quantum-Dot Cellular Automata (QCA) is an important name. It overcomes the serious technical limitations of CMOS at the nano level In this article, we have used two-dimensional two-dot one-electron QCA cells to design a binary to BCD converter. We have justified our proposed design by determining the polarity of different cells including output cells using coulomb law to justify its effectiveness. Finally, we have discussed the issues related to energy and power dissipation in order to drive the proposed architecture.

To enhance the imperceptibility and robustness against image processing operations, the advantage of artificial neural network (ANN) and machine learning algorithms such as support vector regression (SVR), extreme learning machine (ELM) etc. are employed into watermarking applications. In this paper, Lagrangian support vector regression (LSVR) based blind image watermarking scheme in wavelet domain is proposed. The good learning capability, high generalization property against noisy datasets and less computational cost of LSVR compared to traditional SVR and ANN based algorithms makes the proposed scheme more imperceptible and robustness. Firstly, four sub images of host image are obtained using sub sampling. Each sub image is decomposed using discrete wavelet transform (DWT) to obtain the low frequency subband. Low frequency coefficients of each sub image are used to form the dataset act as input to LSVR. The output obtained by trained LSVR is used to embed the binary watermark. The security of the watermark is enhanced by applying Arnold transformation. Experimental results show the imperceptibility and robustness of the proposed scheme against several image processing attacks. The visual quality of watermarked image is quantified by the peak-signal-to noise ratio (PSNR) and the similarity between the original and extracted watermark is evaluated using bit error rate (BER). Performance of the proposed scheme is verified by comparing with the state-of-art techniques.

Emotion Recognition always has been one of the key areas in human machine interaction, machine learning or affective computing. Two dimensional valence arousal model has been used here. In this paper, we present how simple emotion recognition can be done by measuring nine basic non-invasive Biological markers or physiological signals including BR [BReathing], ECG [ElectroCardioGram], EMG [ElectroMyoGram], GSR [Galvanic Skin Response], HR [Heart Rate], PR [Pulse Rate], RR [Respiration Rate], and ST [Skin Temperature] on thirty healthy subjects. Pictorial emotional stimuli categorized as High Valence High Arousal [HVHA], High Valence Low Arousal [HVLA], Low Valence High Arousal [LVHA] and Low Valence Low Arousal [LVLA] were shown using International Affective Picture System (IAPS) for approximately thirty minutes. Six features from each signal were extracted for analysis. Different types of classification algorithms like QDC [Quadratic Discriminant Classifier], kNN [k Nearest Neighbour], Naive Bayes and LDA [Linear Discriminant Analysis] were used in classification of data. Maximum accuracy around 75% for each classifier was obtained. Further improvements are required to make this more robust and to deploy commercially.

This paper considers two dimensional valence-arousal model. Pictorial stimuli of International Affective Picture Systems were chosen for emotion elicitation. Physiological signals like, Galvanic Skin Response, Heart Rate, Respiration Rate and Skin Temperature were measured for accessing emotional responses. The experimental procedure uses non-invasive sensors for signal collection. A group of healthy volunteers was shown four types of emotional stimuli categorized as High Valence High Arousal, High Valence Low Arousal, Low Valence High Arousal and Low Valence Low Arousal for around thirty minutes for emotion elicitation. Linear and Quadratic Discriminant Analysis are used and compared to the emotional class classification. Classification of stimuli into one of the four classes has been attempted on the basis of measurements on responses of experimental subjects. If classification is restricted within the responses of a specific individual, the classification results show high accuracy. However, if the problem is extended to entire population, the accuracy drops significantly.
