Face Recognition using Segmental Euclidean Distance

Farrukh Sayeed, Madasu Hanmandlu, Abdul Quaiyum Ansari
2011 Defence Science Journal  
<p>In this paper an attempt has been made to detect the face using the combination of integral image along with the cascade structured classifier which is built using Adaboost learning algorithm. The detected faces are then passed through a filtering process for discarding the non face regions. They are individually split up into five segments consisting of forehead, eyes, nose, mouth and chin. Each segment is considered as a separate image and Eigenface also called principal component analysis
more » ... (PCA) features of each segment is computed. The faces having a slight pose are also aligned for proper segmentation. The test image is also segmented similarly and its PCA features are found. The segmental Euclidean distance classifier is used for matching the test image with the stored one. The success rate comes out to be 88 per cent on the CG(full) database created from the databases of California Institute and Georgia Institute. However the performance of this approach on ORL(full) database with the same features is only 70 per cent. For the sake of comparison, DCT(full) and fuzzy features are tried on CG and ORL databases but using a well known classifier, support vector machine (SVM). Results of recognition rate with DCT features on SVM classifier are increased by 3 per cent over those due to PCA features and Euclidean distance classifier on the CG database. The results of recognition are improved to 96 per cent with fuzzy features on ORL database with SVM.</p><p><strong>Defence Science Journal, 2011, 61(5), pp.431-442</strong><strong><strong>, DOI:http://dx.doi.org/10.14429/dsj.61.1178</strong></strong></p>

An efficient tree-based topology for network-on-chip

Mohammad Ayoub Khan, Abdul Quaiyum Ansari
2011 2011 World Congress on Information and Communication Technologies  
The increasing demand of numerous applications in consumer electronics has increased the number of computing resources in single chip. In such scenario, application needs many computing resources to build a System-on-Chip (SoC).Therefore, interconnection among Intellectual Property (IP) cores becomes another challenging issue. The performance of the network is measured in terms of throughput. The throughput and efficiency of interconnect depends on network parameters of the topology.Therefore,

This works considers the design of an efficient tree-based topology to apply for Network-on-Chip. The degree of proposed topology is 25% less than the torus along with drastic reduction in the diameter of proposed topology. We have obtained reduced degree for proposed topology that varies from 3 to 6 for the network with k layers, while the diameter of topology is obtained as D= (2n-1) + k -1. We have also presented and simulated an efficient routing algorithm that computes shortest path in the network.

Token based distributed dynamic channel allocation in wireless communication network

Abdul Quaiyum Ansari, Premchand Saxena, Koyel Datta Gupta
2014 CSI Transactions on ICT  
Channel allocation in wireless communication network plays a crucial role in the performance of the network. Fixed scheme for channel allocation does not account for any non-uniform traffic in the network. Dynamic scheme, on the other hand, ensures that whenever a cell requires a channel, it is allocated pertaining to the frequency reuse constraints. The fact that distributed dynamic channel allocation technique has recently gained popularity is due to its high reliability and scalability. In

We will show through simulation, how message exchange between cells is reduced in token based relaxed mutual exclusion as opposed to other relaxed mutual exclusion techniques.

DESIGN OF TRIPLE-BAND MIMO ANTENNA WITH ONE BAND-NOTCHED CHARACTERISTIC

Amit Kumar, Abdul Quaiyum Ansari, Binod Kumar Kanaujia, Jugul Kishor, Nidhi Tewari
2018 Progress In Electromagnetics Research C  
A microstrip-fed two-port multiple-input-multiple-output (MIMO) antenna has been designed for triple-band applications covering the entire ultra-wideband (UWB) with one band-notched characteristic. A defected ground structure (DGS) has been used to obtain a wideband resonance. A crescent ring has been etched on each of the two circular patch antennas to produce a band-notch characteristic centered at 5 GHz, ranging from 3.96 to 6.2 GHz. These introduce notches at 5.2/5.8 WLAN, 5.5 WiMAX, LMI

The proposed MIMO antenna elements have been isolated by more than 16 dB throughout the operating band using a modified inter-digital capacitor (MIDC) placed between the circular patch antennas. The MIDC also helps in achieving a center-band, ranging from 6.2 to 8.93 GHz and is useful in IEEE INSAT/Super Extended C-band. The lower-band ranges from 3.08 to 3.96 GHz and covers 3.5 GHz WiMAX while the upper-band, ranging from 10 to 16 GHz, is useful for X-band and Ku-band applications. Finally, the MIMO antenna has been fabricated on an FR-4 substrate of dimensions 50×30×1.6 mm 3 with a compact antenna area of 0.158λ 2 0 . All results along with the diversity performance have been experimentally verified.

To enumerate the efficiency and the generalization capability of the predictors, the performance of the model is investigated in terms of mean square error (MSE) and mean relative error (MRE). A very good agreement is found between the measured S-parameters and the proposed model for multi-biasing sets over the complete frequency range of 1 GHz-18 GHz. The proposed technique is even used to test the frequency extrapolation capability of the model. A comparative analysis indicates that the proposed PSO-SVR predictor achieves significantly improved computational efficiency and the overall prediction accuracy. To demonstrate the ready usefulness of the modeling approach, the developed model has been incorporated in CAD environment using MATLAB Cosimulation in ADS Ptolemy. Subsequently, the small-signal stability analysis is performed and gain of a power amplifier configuration designed using the proposed GaN HEMT model is determined.

The potential usefulness of the proposed filter is additionally incontestable through the Total Harmonic Distortion (THD), Power Supply Rejection Ratio (PSRR), Temperature sweep, Corner, Supply Voltage variation and Noise Analysis. It has been observed that the proposed pass filter in fractional domain supported OTRA provides greater flexibility in controlling the magnitude characteristics.
