Automatic face detection and recognition is a challenging problem which has received much attention during recent years due to its many applications in different fields. Face recognition is one of those challenging problems and up to date, there is no technique that provides a robust solution to all situations. In this paper we are presenting an algorithm for face detection in an image using skin...
In this paper, a novel switching mean filter using cloud algorithm method is proposed, which is a powerful impulse noise removal method. We employ an efficient impulse noise detector to detect the noisy pixels and proposed cloud impulse noise removal algorithm to reconstruct the intensity value of noise pixels. Extensive experimental results demonstrate that our method can obtain better performances...
Image demosaicing is a problem of interpolating full-resolution color images from so-called color-filter-array (CFA) samples. Among the various CFA patterns, Bayer pattern has been the most familiar choice and demosaicing of Bayer pattern has attracted renewed interest in the recent years. In this paper we propose a new modified color filter array interpolation method which uses the spatial filters...
This paper presents on the analysis of static and dynamic power dissipations in the proposed 10T SRAM cell. In the proposed structure two voltage sources, one connected with the Bit line and the other connected with the Bit bar line for reducing the voltage swing during the switching activity. This reduction in voltage swing causes less dynamic power dissipation during switching activity. Two stack...
This paper focuses on the power dissipations at different supply voltages, bit line capacitances and stability analysis at different pull-down ratios of a novel low power 12T MTCMOS SRAM cell. Because of MTCMOS technology, the SRAM cell is having low VT (LVT) transistors and there are two high VT (HVT) Sleep transistors as well. Sleep transistors and a LVT Transmission gate (TG) in conjunction are...
The modern era of digital communication facilities bring digital watermarking techniques which is required to copyright and authenticate owner's information which further tracks control of regeneration and redistribution of images over untrusted and public network. In this paper, a blind digital watermarking technique has been proposed using Discrete Cosine Transform (DCT) to embed information in...
Cell size breathing can lead to the generation of coverage holes in the busy hour. There are chances of call drops and handoff failures when UE moves into the region with insufficient signal levels less than minimum UE receiver sensitivity. So the theme of the paper is to increase the vertical beam width of the antenna array in the busy hour so that it overlap the cells and increase the handoff success...
In video both temporal redundancies as well as spatial redundancy occurs. So to remove the both type of redundancies we need combination of systems that can remove both type of redundancies and hence we use Hybrid Video Codec for video compression. In encoder part of Hybrid Codec, we find the motion vector (MV) of the candidate block of current frame in reference frame using block based motion estimation...
Acoustic echo is one of the most important issues in communication. It creates disturbance in day-to-day communication. This echo can be cancelled using adaptive filters which are governed by adaptive algorithms. Right from the introduction of Least Mean Square (LMS) algorithm, over the years, a lot of research has been done in this field in order to develop new algorithms which can effectively drive...
Unconstrained acquisition of data from arbitrary subjects results in facial scans with significant pose variations. The challenges in 3D face recognition are into two main stages, namely preprocessing range scans for detection of fiducial detection while identifying/filling missing parts due to occlusions along with outlier noise reduction and during post-processing where actual match is done with...
The mobile ad hoc networks is an attractive field to the researchers for its ease in deployment and maintenance. In this work, we focus on the optimization of energy consumption and stability of the node which has become a critical issue in ad hoc networks. Clustering of nodes is one of the significant means to extend lifetime of the network. This paper proposes Ant Colony Optimization (ACO) approach...
This novel work is aimed at the study of emotion recognition from gestures using Kinect sensor. The Kinect sensor along with Software Development Kit (SDK) generates the human skeleton represented by 3-dimensional coordinates corresponding to twenty body joints. Using the co-ordinates of eleven such joints from the upper body and the hands, a set of nine features based on the distances, accelerations...
When we consider an industry of large area the monitoring, controlling of each section involved in the industry is a big task. It involves a large amount of man power and time consumption. To overcome these above factors we developed this technology to make single person for monitoring and controlling the entire network. This can be achieved based on multiprocessor communication by the combination...
