Due to factors like presence of inactive frames, inter-view dependencies and frequent illumination changes, whole video content may not be important. Moreover, users may not have the adequate time to access/ store the entire video in real time. We propose a machine learning ensemble method to summarize the events in multiview videos, as a solution to the aforementioned issues. In order to make the accurate decision on keyframes, we trained our ensembles using meta approach where the inter-dependency and illumination changes of views are considered in the training phase. Experimental results on two benchmark datasets show that our model outperforms the state-of-the-art models with the best Recall and F-measure. The computing analysis of the model also indicates that it meets all requirements of real-time applications.","PeriodicalId":383252,"journal":{"name":"2017 International Conference on Innovations in Electronics, Signal Processing and Communication (IESC)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128588964","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 proposed antenna is derived from a rectangular microstrip patch antenna and it consists of three parasitic patches near to radiating edge of the main radiator. PIN diodes are incorporated to provide necessary electrical connectivity between the main radiator and the parasitic patches.

The antenna is studied and designed using computer simulation tool and offers frequency reconfigurability over a frequency range of ∼ 1.0 GHz (5.05 GHz–5.98 GHz).

The input core utilizes two complementary PMOS and NMOS input pairs to ensure rail-to-rail input common mode range (ICMR). The cascoded load structure at output port performs the job of current summer and provides enhanced gain due to high output impedance for FCOTA. The proposed OTA has been employed to implement universal biquadratic low-pass, high-pass, band-pass and notch transfer functions, simultaneously available at different nodes of the filter. The proposed FCOTA used dual supply voltage of ± 0.9V and dissipates around 93.6 μW power and provides 80.24 dB open loop gain and gain bandwidth (GBW) of 6.03 MHz.

Offloading of user traffic from macro tier to small cell tiers is the concept of Heterogeneous Networks (HetNets) but this lead to problems like densification of cellular structure, interference in various tiers, complexity and cost. The key contribution of this paper includes enhancing Spectrum Efficiency (SE) and Energy Efficiency (EE) via biased Intra or Inter RAT offloading. This is done by formulating a multi-objective optimization problem in which both SE and EE are maximized subject to constraints of minimum attainable throughput in both Radio Access Technologies and genetic algorithm is used to solve this problem. Moreover, the channel modeling is in accordance with standard 3GPP specifications which capture the expectation of real scenario in our objective function.

In this paper, fully automatic lung field segmentation is proposed. Initially, novel features are extracted by considering spatial interaction of the neighbouring pixels. Then constrained non-negative matrix factorization (CNMF) factorized the data matrix obtained from the visual appearance model into basis and coefficient matrices. Initial lung segmentation is achieved by applying unsupervised learning on the coefficient matrix. 2-D region growing operation removes trachea and bronchi appearing in the initial lung segmentation.

The working of PCA is based on the optical-to-electrical power conversion technique. The main advantage of the PCA is that it can be used both as a source as well as a detector with little changes in the operating mechanism. In literature, several experimental, simulation and theoretical studied are available for PCA operating as a source. However, very few experimental and simulation studies are available to analyze the performance of PCA as a receiver. In this communication, an effort has been made to analyze the performance of a PCA as a receiver by modeling an equivalent electrical circuit of it, which is based on the physics involved in its operation.","PeriodicalId":383252,"journal":{"name":"2017 International Conference on Innovations in Electronics, Signal Processing and Communication (IESC)","volume":"107 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120884028","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}
