It is seen that localization of the optic disc and retina vessel segmentation is considered as the first step of retinal disease diagnosis and identification algorithm [2], [3]. In this paper algorithm discussed consist of two stages. The first stage is detection of blood vessels using median filtering for background estimation on green channel followed by morphological operation on retinal images. Structural element (SE) is selected in such a way that only main blood vessels are detected. The second stage involves localization of OD. For localization of OD its property of being most bright portion of retinal image is used and histogram matching approach using KL divergence method followed by main vessel verification is used. To evaluate the proposed algorithm we use DRIVE publicly available eye fundus image databases contains 40 images and it achieves accuracy of 100% in locating a point in OD and also on 20 images of STARE database out of which we localize OD in 18 images accurately.","PeriodicalId":318875,"journal":{"name":"2015 International Conference on Signal Processing and Communication (ICSC)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131370207","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}

At Ts = 350 °C, the room 4πMs reached the maximum of 3 kG. The films were studied by spectral ellipsometry and magnetooptical (MO) Kerr effect spectroscopy at photon energies between 1 and 5 eV at room temperature in the longitudinal magnetic flux density 1.14 T. The optical and MO spectra show structural details typical for inverted spinels. Our ZnFe2O4 samples display amplitudes somewhat reduced with respect to those in other ferrimagnetic oxides with the exchange coupled Fe3+ pairs, i.e., in Li0.5Fe2.5O4 and MgFe2O4 spinel ferrite and magnetoplumbite, PbFe12O19. The lower amplitudes are probably due to the interplay of nanocrystalline nature and lower degree of spinel inversion in the ZnFe2O4 laser ablated films.","PeriodicalId":318875,"journal":{"name":"2015 International Conference on Signal Processing and Communication (ICSC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131843205","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}

An important characteristic of imaging sensor is resolution which is classified in four different ways: (a) spatial; (b) spectral; (c) radiometric; and (d) temporal. During recent decades, the emergence of multispectral sensors provides the data with enlarged quantity of spectral bands and change in different spectra often correspond to alterations in some vital surface physical parameters. The higher spectral resolution Moderate Resolution Imaging Spectroradiometer (MODIS) sensor delivers data in 36 different spectral bands at three different spatial resolution to enhance the applications of remote sensing. Additionally, MODIS sensor has great temporal resolution which helps in updating of information on nearly daily basis. Beforehand to any application, various pre-processing procedures must be implemented to the remote sensed imagery to enhance different appropriate features. In case of undulating region imagery, it is important to eliminate the topographic effects such as shadowing, which generally, found in the remotely sensed images acquired from Himalayan region. From this perspective, this paper involves the analysis of impact of topographic correction on multispectral MODIS sensor data of Himalayan region. In the referred study, the base map of study area was derived from Himalayan region in which recover the information is problematic due to presence of topographic effects. Experiment conclusions confirmed that topographic corrections are significant in attaining a better quantification and understanding of a wide variety of procedure occurring in atmosphere and on the Earth surface. Moreover, extensive field investigation beyond that covered in this work is mandatory to assess the exact extent of the impact of the different spectral bands of different satellite sensors on topographic corrections.","PeriodicalId":318875,"journal":{"name":"2015 International Conference on Signal Processing and Communication (ICSC)","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116417445","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 design has two level stepped corners (lower) at the radiating patch along with two inverted L shaped slots on the two non-radiating edges of the microstrip patch antenna. The dimensions of the two L slots are optimized so as to achieve the U-NII band rejection (5.15 GHz to 5.825 GHz). The proposed antenna is designed and simulated using Computer Simulation Technology Microwave Studio (CST-MWS). This antenna operates in a frequency band ranging from 2.79 to 11.03 GHz with a band rejection from 4.88 to 5.94 GHz. The dimension of the proposed design is 27.00 mm (L), 32.42 mm (W) and 1.7 mm (H). The VSWR is less than 2 for entire operating frequency range. The impedance bandwidth of the proposed design is nearly 7.18 GHz with band rejection. This antenna can be used in various applications in 3.5 GHz WiMAX, 4 GHz C band and lower frequencies of X band without interference from U-NII (Unlicensed National Information Infrastructure) band. The effect of the partial ground plane and the dimensions of stepped corners with two inverted L slots are optimized for better return loss, whose parametric study is discussed in detail.","PeriodicalId":318875,"journal":{"name":"2015 International Conference on Signal Processing and Communication (ICSC)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124039923","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}
