We also discuss the summary evaluation criteria and compare the approaches based on the method, data set and the results. Video Summary is a process of presenting an abstract of entire video within a short period of time. It aims to provide a compact video representation, while preserving the essential activities of the original video. It is an essential task in video analysis and indexing applications. Most of the video summaries are based on selection of key frames within the shots of a video. Many of them use motion features and few use visual features for extracting the key frames. The video summary quality assessment methods are based more on subjective and less on objective measures. Tong wei Ren et al has provided a framework to assess the quality of the video against a given reference summary using both subjective and objective measures. Ciocca et al used the objective measures for evaluation of summary and most of them evaluate by taking the subjective opinion of experts. A framework for automatic evalution is needed based on both subjective and objective measures without the reference summary.","PeriodicalId":292190,"journal":{"name":"2011 International Conference on Computational Intelligence and Communication Networks","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125087594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally the design of wireless systems has been focused on increasing the reliability of the air interface where fading and interference are viewed as nuisances. Recent focus is now on spectral efficiency, associated with this shift is a new point of view that fading can be viewed as an opportunity to be exploited. In the initial stages, the single antenna system was used at transmitter and receiver in both the sides (SISO system) anticipating lower spectral efficiency and lesser capacity. It can be seen that root cause of the poor performance of these technique is that reliable communication depends on the strength of the single signal path only which may be in a deep fade under certain circumstances. A natural solution is to ensure that the information symbols pass through multiple signal paths, each of which fades independently, making sure that reliable communication is possible as long as one of the paths is strong. This technique is called diversity. The main objective of this paper is to achieve the greater reduction in bit error rate in 4G wireless system using antenna diversity principles along with efficient wireless channels. The quality based simulation models are developed for WiMAX system using antenna diversity technique and real time image input. The simulation results are presented along with the comparative analysis for several test cases.","PeriodicalId":292190,"journal":{"name":"2011 International Conference on Computational Intelligence and Communication Networks","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130287235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Land Cover information like vegetation, water bodies, rocky area, sandy area etc. and its change over a period of time greatly affect local, regional and global environmental changes. Land Use information like buildings, roads and railway tracks are important features of urban infrastructure which crucially affect the life of people in cities. Recent developments in biologically inspired optimization techniques have motivated the researchers to explore the application of these techniques to the problem of satellite image feature classification. In this paper particle swarm optimization (PSO) along with the morphological operators is used for the identification of urban features like road and railway network, as well as land cover types, contained in the image. The concept of this paper is to explore and utilize the neighborhood information of the swarm computing algorithm to accurately identify features in the natural terrain environment. The test areas used are located in urban environment of Chandigarh and Saharanpur. Google Earth images of these areas were acquired and processed. The approach adopted has yielded satisfactory results.","PeriodicalId":292190,"journal":{"name":"2011 International Conference on Computational Intelligence and Communication Networks","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127390063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MAGIC is used as two-dimensional CAD layout tool. Also PSPICE is used for electrical simulation purposes employed by extraction tool. Feature size is taken from mSCN3M_SUBM.30 process for 0.6μm layout and 0.5μm enhanced fabrication process. The improved design has area of 101?X48? (minimized from 126?X59?) or 30.3μmX15μm (minimized from 37.8μmX17.7μm) in 0.6?m CMOS design process. For multi-die placement, two sets of chip are designed those are placed on the four sub-dies in a single MOSIS tiny chip die. For one set of chip coincidence detector is designed to make the mirror-amplifier ultra precise, buffer stage is designed for another set of chip to drive large load.

Different noise densities have been removed by using four types of filters as meidan filter, Lee filter, Kuan filter, Frost filter, and Wavelet based Bivariate Shrinkage function. Synthetic aperture radar (SAR) images are inherently affected by multiplicative speckle noise, which is due to the coherent nature of the scattering phenomenon. Multiwavelet transform technique has a big advantage over the other techniques that it less distorts spectral characteristics of the image denoising We apply the proposed method for speckle SAR images by using logarithmic transformation. We present a novel approach to estimating the mean square error (MSE) associated with any given threshold level in both hard and soft thresholding This paper proposes different filtering techniques based on statistical methods for the removal of speckle noise.. The quality of the enhanced images is measured by the statistical quantity measures: Noise Variance, Mean Square Error (MSE), Equivalent Numbers of Looks (ENL), Signal-to-Noise Ratio (SNR), and Peak Signal-to-Noise Ratio (PSNR),","PeriodicalId":292190,"journal":{"name":"2011 International Conference on Computational Intelligence and Communication Networks","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131292995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
