There are several type of approaches used for this but they have high computational complexity. But scientist needs to study fish populations underwater in different environmental conditions. In this paper we proposed a simple algorithm for tracking and detecting multi moving fishes. A huge number of fishes can be tracked by comparing its mean in the successive frame of the video. The obtained output states a measurement of the difference of two mean values. The object window contains the matrix of the intensity value. Then this value is transformed into a set of feature vector. Finally the above two set of features is compared in the successive frame for a good match to its nearest locality. The MatLab 8.0 simulation result shows that the proposed method is capable of accurately detecting with high detection rate as compared to existing approaches with noisy and dense environment.","PeriodicalId":352568,"journal":{"name":"2015 International Conference on Microwave, Optical and Communication Engineering (ICMOCE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123377746","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}

Among a set of N relay elements, the Nth Best-Relay Selection scheme is proposed. The selection algorithm shows improvement in the bandwidth penalty and also increases the spatial diversity by employing a sub-optimal allocation considering the relay relative distance between the source and destination in a multi-hop cooperative systems. A single branch dual-hop network with adaptive Decode-and-forward (DF) and Amplify-and-forward(AF) cooperative diversity systems is considered. The analytical model of the proposed Nth Best-Relay selection scheme over single branch dual-hop system was developed and a closed-form expression was obtained. The BER (Bit error rate) and Outage probability using binary and quadrature phase shift keying modulation schemes (BPSK & QPSK) employing decode-and-forward (DF) and amplify-and-forward(AF) cooperative diversity systems over Nagakami fading channel was estimated. Results show that in the Nth best relay the diversity order is equal to (M - N + 2) where M is the number of relays.","PeriodicalId":352568,"journal":{"name":"2015 International Conference on Microwave, Optical and Communication Engineering (ICMOCE)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132650840","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}

With the use of appropriate background clutter model, CFAR detection algorithm is applied to moving and stationary target acquisition and recognition (MSTAR) data.

A simple and efficient impulse detector known as Min-Max impulse detector (MMID) is utilized for impulse detection. The detector classifies the pixels into noisy and noise free based on the dynamic range of an image. A pixel is identified as noisy if its intensity value coincides with the minimum or maximum value of the dynamic range. The noisy pixels are restored using the median of noise free pixels and noise free pixels are retained as it is. The experimental analysis declares that MMID is good at identifying the pixels corrupted by fixed valued impulses and enhances the performance of a median filter.","PeriodicalId":352568,"journal":{"name":"2015 International Conference on Microwave, Optical and Communication Engineering (ICMOCE)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127349805","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 Non Linear effects have been related with the intensity and thus most of the work has been directed towards the study of input power to depreciate the limitations imposed by the Non Linearities. In this paper a methodology to decrease the combined effect of SRS, FWM and ASE Noise and to minimize the Bit Error Rate has been suggested by optimizing Inter Amplifier Separation for a 10 Gbps WDM system for link lengths up to 500 Kilometers using Simulation. Optimization of interamplifier separation improves the BER and thus the system length can be extended. Also the nature of ASE and FWM effects has been studied and it has been shown that the system performance is most affected by the FWM effect.","PeriodicalId":352568,"journal":{"name":"2015 International Conference on Microwave, Optical and Communication Engineering (ICMOCE)","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122977352","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}
