This paper presents a hybrid pansharpening method based on MRA framework and the sparse representation of injected details. To add spatial details of the panchromatic image into the multispectral image more effectively, the injection gains are computed through an iterative full-scale model in which the gains are updated at each iteration relying on its previous iteration’s fusion product. The proposed method is compared with five pansharpening approaches to investigate the effectiveness. Experiments have been implemented on two data sets from the Pleiades and GeoEye-1 satellites both at reduced and full scale. In terms of visual and quantity assessment, the high-resolution MS image produced by the proposed method is more acceptable than those images fused by other rival approaches.","PeriodicalId":6797,"journal":{"name":"2020 IEEE India Geoscience and Remote Sensing Symposium (InGARSS)","volume":"110 1","pages":"86-89"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73026612","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}

It is a basaltic shield volcano with a summit caldera of dimension 5 x 6.5 km. Recently, the volcano erupted on January 12, 2020, preceded by a seismic shock of magnitude 4.7 at a depth of 5 km. The subsequent seismic activities have led to the formation of a circumferential fissure below the La Cumbre crater's eastern rim, at an elevation of 1.3-1.4 km. The lava flow has occurred down the flank to the sea through this fissure. This volcanic episode has continued up to 9 hours. The InSAR time series method is a multi-temporal InSAR technique used to detect slowly occurring deformations with a millimeter level of precision using a stack of SAR interferograms. In this paper, the Differential InSAR has been used to analyze Fernandina volcano's surface deformation due to this recent eruption. The interferograms of the volcano before, during, and after the eruption have been analyzed in detail using the freely available Sentinel 1 C- band datasets from 2019 December 17 to 2020 February 09. The integration of all these analyses gives an insight into the underground magma conduit system, the correlation between the magmatic and seismic activities, surface deformations, and the lava flow channels, which have been discussed in detail in this paper.","PeriodicalId":6797,"journal":{"name":"2020 IEEE India Geoscience and Remote Sensing Symposium (InGARSS)","volume":"188 1","pages":"250-253"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85459326","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}

Reflectance spectra of muscovite has several diagnostic absorption features in wavelength range 0.4-2.5 µm. The absorption feature near 2.20 µm is sensitive to alumina content variations. In this study, we use reflectance spectra of powdered muscovite and geochemical datasets to quantify the relationship between spectral shift and alumina content. Imaginary index of refraction (k) was derived from reflectance spectra and a linear model was proposed relating alumina content and k. Reflectance spectra of muscovite was modelled for varying alumina content and grain size using Hapke model. Modelled spectra shows shift in wavelength position of 2.20 µm with varying alumina content and deepening of absorption features with increase in grain size.

Even though there is an extensive number of methods developed for object detection, there are still several challenges that remain unsolved, such as visual appearance variations, occlusions, and background clutter. Satellite images reveal a texture problem; it is difficult to differentiate between the background and the object of interest. In order to overcome this problem and exploit more of the spectral features of images, Discrete Wavelet Transform (DWT) is embedded into one of the most superior methods for object detection, which is Faster Region-based Convolutional Network (FRCNN). The accuracy of FRCNN is boosted by introducing the wavelet decomposition. The performance of the proposed strategy is tested, evaluated, and compared to the original FRCNN using two different datasets.","PeriodicalId":6797,"journal":{"name":"2020 IEEE India Geoscience and Remote Sensing Symposium (InGARSS)","volume":"31 1","pages":"106-109"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80360950","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}

This paper proposes a new 3D-Deep Feature Extraction CNN model for the HSI classification which uses both spectral and spatial information. Here the HSI data is divided into 3D patches and fed into the proposed model for deep feature extractions. Experimental results show that the performance of HSI classification is improved significantly with the proposed model. The experimental results on the publicly available HSI datasets, viz., Indian Pines(IP), Pavia University scene(PU) and Salinas scene(SA), are compared with the contemporary models.

Endmember extraction is the most decisive task in hyperspectral image analysis. Endmember initialization algorithms (EIAs) play a key role and support endmember extraction algorithms (EEAs) in extracting near optimal set of endmembers. Though there are few endmember initialization techniques available, similarity measures are not explored in detail in target generation. Hence, in this paper, it is proposed to explore similarity measures in identifying spectrally distinct signatures to use them as initial endmembers. Individual similarity measures are combined to form hybrid similarity measures to confirm their effectiveness in generating spectrally distinct targets. Initial set of endmembers extracted by proposed algorithm are used for initializing classical EEA, the NFINDR, which is sensitive to endmember initialization, and their performance in final endmembers selection is verified. Experimental results on two hyperspectral data sets show the superior performance of the similarity based endmember initialization algorithm (SMEIA).","PeriodicalId":6797,"journal":{"name":"2020 IEEE India Geoscience and Remote Sensing Symposium (InGARSS)","volume":"12 1","pages":"221-224"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90102118","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}
