Dynamic Stochastic Resonance (DSR) utilizes the noise associated with the image itself to enhance the image quality. This paper analyzes the effects of Discrete Wavelet Transform (DWT), Discrete Cosine Transform (DCT) and Singular Value Decomposition (SVD) of image, which works as the input to bi-stable nonlinear system exhibiting DSR. The study performed on T1, fluid-attenuated inversion recovery...
Wireless sensor based communication system is an ever-growing sector in the industry of communication. The Wireless sensor network (WSN) is expected to play significant role in future internet and wireless based application service delivery such as in healthcare, environment monitoring etc. However the existing radio network is crowded due to increase in use of wireless technology such as Wi-Fi, Bluetooth...
Cloud computing offers an economical solution to the computationally weak clients. It enables the client to execute large computations beyond their computation capacity by outsourcing their computation load to the massive cloud servers. However, outsourcing of data and the computation to a third-party cloud server bring many security and privacy concern. In this paper, we are addressing the problem...
Sound is only the important way of human perception on the world, but also reflects some important characteristics of human behaviors under certain circumstances. This paper mainly presents the sound event recognition method using Mel-frequency Morlet wavelet subband (MFMWS) feature and sparse representation-based classifier (SRC) aiming at security monitoring applications. In order to evaluate its...
Proper extraction of words from handwritten documents is a tedious task. In this paper we discuss an effective method for binarization of handwritten document images. Document binarization is a preprocessing step for the recognition of offline handwritten words. Various techniques used for binarization are discussed in this paper. The proposed method is evaluated and got good results. This approach...
Medical Image retrieval and similar image classification are the two important aspects in decision making and automatic medical image annotation. These approaches help the doctors and radiologists in their decision making during decease identification and decision making. Image classification is usually done by checking image visual content or semantic content similarity. Image content may be represented...
A Broadband Microstrip U-slot antenna with improved impedance bandwidth has been presented. The measured impedance bandwidth of a reflection coefficient in −10dB ranges from 1.22 to 3.77 GHz and thus covers most of the commercial wireless communication systems, such as SDAR(2.32–2.35) GHz, WLAN(2.4–2.5) GHz, PCS(1.8–2.0) GHz. To achieve compact size the square patch is embedded with a U-slot, and...
In Fiber optic communication, Dense Wavelength Division Multiplexing system (DWDM) is used to increase the capacity and to satisfy the need of enormous bandwidth utilization. In this system more number of channels with different wavelength passed through Single Mode Fiber (SMF). Eventhough, there is an impact of parameters such as input power, channel spacing and frequency response. To achieve high...
In recent days, a number of face recognition and authentication mechanisms are developed in the computer vision applications. The human faces may be obstructed by other object that makes the acquisition of fully holistic image processing as a complex task. To overcome this problem, a new partial face recognition system is introduced in this paper. This work includes the preprocessing, face detection,...
Multisensor image fusion is the process of combining relevant information from high spatial resolution image and high spectral resolution image. This paper proposes a new image fusion method based on Dual Tree-Complex Wavelet Transform (DTCWT), and Curvelet transform for remotely sensed lunar image data in order to extract features accurately. Different fusion techniques have been used in the past...
There are different types of Microfluidic particles sorting devices have been developed, but most of those devices have limitation in terms of the relatively low throughput. In this which method has been used is Hydrodynamic Filtration through which sorting of Bacteria particles (Beads or cells) from given sample medium can be separated which are of different size. A new scheme has been describes...
The Cognitive Radio (CR) is an emerging technology for modern wireless communication system that offers a great solution to scarcity of radio spectrum. The Cognitive Radio Network (CRN) is an intelligent wireless communication organization that is aware of its environment. Here, heterogeneous nodes meet spectrum sensing challenges due to the variation of transmission power, spectrum allocation and...
This work deals with the hardware implementation of the Consultative Committee for Space Data Systems File Delivery Protocol, using Consultative Committee for Space Data Systems Packet Service and Telemetry/Telecommand framing schemes, which is less software intensive, to replace highly CPU intensive architectures for reliable space communication. A low latency, low area, intelligent programmable...
In this paper, a phased array monopole radiator with and without absorber for ultra broadband applications is presented. The proposed operates over 2–18 GHz and has dimension of 21 mm × 31 mm × 1.9 mm. The simulation result shows that VSWR is less than 2.0 in the specified frequency band. It is shown that the radiation pattern of bidirectional antenna is omni-directional in elevation and bidirectional...
