The compound K-distribution model finds excellent agreement with high-resolution radar backscattering from sea surfaces. In order that the stochastic properties of sea clutter be predicted correctly, the measures developed for the statistical models must comply with those obtained from experimental data. In this paper, the stochastic properties of correlated K-distributed clutter are investigated by rigorous tests of validation. Statistical tests adopted in the paper are compared with high-resolution IPIX radar experimental database.

Beamforming technique is being used in sensor networks to enhance its communication range. The sensors in a networks work on their own clock and for distributed beamforming these signals coherently add at the destination. For this, the knowledge of the channel state information is required. Since the channel state information (CSI) is not available at the transmitter side, the retracement technique is used to estimate the channel effect. In this paper, a novel Semiblind retracement technique is proposed to improve the data transfer rate. The semiblind retracement technique is considered for the cases of a 1 bit feedback and for no reliable feedback mechanism from destination. The sensor distribution is considered as uniform and gaussian and the channel is modeled as Rayleigh and Rician distributed. Simulation results indicate that the proposed semiblind method results in improved data rate. The efficiency is about 9.1% increase in data transmission rate for the worst case channel variation assuming retracement slot is 20% of transmission slot and with 3dB reduction in gain.

Dynamic logic style is used in high performance circuit design because of its fast speed and less transistors requirement as compared to CMOS logic style. But it is not widely accepted for all types of circuit implementations due to its less noise tolerance and charge sharing problems. Domino logic uses one static CMOS inverter at the output of dynamic node which is more noise immune and has less capacitance at the output node. In this paper we have proposed a novel circuit for domino logic which less noise at the output node and has very less power-delay product (PDP) as compared to previous reported articles. The proposed circuit is being compared with previous reported domino logic and the basic domino logic structures in different ways and found to be having least PDP from others.

Traditionally, thumb print and iris pattern are used for person identification as biometric features. Use of ear is recent biometric evolution for identification. A system is presented here for person identification using ear features. Digitally captured ear image is processed to extract ear features (Helix rim, Lobule, Triangularfossa, Concha and Tragus) and stored in database for matching process. Matching process uses projection lines to quantify ear features. Matching process gives matched profile as a result of system in graphical format as well as textual format with tolerance limit of ± 15%.

Multiplication is fundamental and significant operation of Electronic Circuits. Low power multipliers with high clock frequencies are widely used in today's digital signal processing. Currently demand is power efficient, high speed miniature system which leads to design circuits with transistor level optimization. Full adder circuit is basic block of multiplier. Transistor level optimization of basic building element directly results in reduction of delay and power. In this paper, the performance analysis of Wallace-tree multiplier architectures are carried out based on small size full adder circuits.

The reversible data embedding is emerging due to its various watermarking and steganography applications. Most of the reversible data embedding schemes result in visual distortions while embedding the data into DCT domain. In this paper we propose a reversible data embedding scheme for MPEG-4 video which embed the data into middle frequency coefficients of quantized DCT blocks and use HVS based visual quality metrics. The relative improvement in the visual quality and capacity is compared and the experimental results show that the proposed scheme achieves higher visual quality.

Beamforming system, we estimate the signal of interest arriving form some specific directions in the presence of noise and interference signals with the help of an array sensors. These sensors are located at different spatial position and sample the propagating waves in space. The collected samples are then processed to null out the interfering signals and spatially extract the desired signal. Finally, specific spatial response of the array system is achieved with beam pointing to the desired signals and null towards the interfering ones. This paper describes the design and implementation, a phase shift beam former. Phase-shift beamforming, although simple to implement, uses the narrowband approximation of time delays. All result produce in matlab and considering with that involved signal is narrow band signal.

Sign Language is a method of communication for hearing and speech impaired people in which hand movements, gestures and facial expressions are used to convey messages. The hearing and speech impaired people are deeply associated with Sign Language as it is their fundamental medium of communication. American Sign Language (ASL) is a complete, visual-gestural language that employs signs made by moving the hands combined with facial expressions and postures of the body. The paper discusses novel Sign Language Image Retrieval techniques using the edge images of the ASL signs. Edge images are obtained by applying gradient masks and Slope Magnitude Methods. The proposed image retrieval techniques are tested on generic image database with 312 images. Feature vector of sign images are extracted using color averaging techniques. In all 5 techniques are experimented and sign images are compared using 5 masks (Prewitt, Robert, Sobel, Laplace, and Canny) and 5 averaging techniques. The GAR (Genuine Acceptance Ratio) values indicate the best performance values.

In recent time face detection is of utmost importance because for its various applications. Several approaches have been implemented to date. This paper aims towards an effort to represent a novel approach for human face recognition. The proposed system consists merging both frequency and spatial domain techniques. The proposed system selects the Region of Interest on which Ripplet Transformation is to be applied after power law transformation to calculate Standard Deviation (SD) and Mean as features. At later stage, Feed Forward Back Propagation Neural Network (FFBPNN) is used for classification and recognition purpose. The approach is tested with non face images to show its effectiveness which is around 91.67%.
