Collaborative Representation-Based Binary Hypothesis Model with Multi-features Learning for Target Detection in Hyperspectral Imagery
Journal of the Indian Society of Remote Sensing - Tập 46 - Trang 847-862 - 2018
Chunhui Zhao, Wei Li
In this paper, we propose a collaborative representation-based binary hypothesis model with multi-features learning (CRTDBH-MTL) for target detection in hyperspectral imagery. The proposed method contained the following aspects. First, two complementary features extracted by different algorithms are implemented for describing hyperspectral imageries. Next, we apply these features into the unified ... hiện toàn bộ
Estimation of chlorophyll-A concentration using an artificial neural network (ANN)-based algorithm with oceansat-I OCM data
Journal of the Indian Society of Remote Sensing - Tập 35 - Trang 201-207 - 2007
P. V. Nagamani, Prakash Chauhan, R. M. Dwivedi
An artificial neural network (ANN) based chlorophyll-a algorithm was developed to estimate chlorophyll-a concentration using OCEANSAT-I Ocean Colour Monitor (OCM) satellite-data. A multi-layer perceptron (MLP) type neural network was trained using simulated reflectances (~60,000 spectra) with known chlorophyll-a concentration, corresponding to the first five spectral bands of OCM. The correlation ... hiện toàn bộ
Description of Salient Features Combined with Local Self-Similarity for SAR Image Registration
Journal of the Indian Society of Remote Sensing - Tập 45 - Trang 131-138 - 2016
Lijuan Yang, Zheng Tian, Wei Zhao, Weidong Yan, Jinhuan Wen
Local feature descriptor plays an important role in image representation and is helpful to further image processing. This paper proposes a local feature descriptor based registration method for synthetic aperture radar (SAR) images. The proposed method starts with identifying evenly distributed features by applying the divided salient image disk (SID) extraction method. To describe the shape conte... hiện toàn bộ
Application of Multi Criteria Decision-Making Technique in Site Selection of Wind Farm- a Case Study of Northwestern Iran
Journal of the Indian Society of Remote Sensing - Tập 44 - Trang 803-809 - 2016
Sahar Rezaian, Seyed Ali Jozi
The aim of this study was to determine suitable areas for construction of wind farm in Takestan Plain as one of the main wind-prone areas in Qazvin Province. To this end, one of the widely-used multi criteria decision making techniques (Analytical Hierarchy Process (AHP)) was used. The site selection criteria were divided into three main groups of environmental, technical and geographical. Further... hiện toàn bộ
A Novel Approach to Estimate Diffuse Attenuation Coefficients for QuickBird Satellite Images: A Case Study at Kish Island, the Persian Gulf
Journal of the Indian Society of Remote Sensing - Tập 41 - Trang 797-806 - 2013
Keivan Kabiri, Biswajeet Pradhan, Helmi Zulhaidi Mohd Shafri, Shattri Bin Mansor, Kaveh Samimi-Namin
Diffuse attenuation coefficient (k d ) is a critical parameter for benthic habitat mapping using remotely sensed data. This research attempted to develop a new approach to estimate k d in blue and green bands of QuickBird satellite image based on the integration of Lyzenga’s method and updated NASA-k d 490 algorithm. To do this, the Lyzenga’s method was utilized to determine the ratio of k d in di... hiện toàn bộ

Remote Sensing and Geographical Information System for canopy cover mapping
Journal of the Indian Society of Remote Sensing - Tập 29 - Trang 107-113 - 2001
Ndr Krishna, A K Maji, YVN Krishna Murthy, BSP Rao
Availability of remote sensing data from earth observation satellites has made it convenient to map and monitor land use/land cover at regional to local scales. A land cover map is very critical for a various planning activities including watershed planning. The spectral and spatial resolutions are major constraints for mapping the crop resources at microlevel. The cropping pattern zones have been... hiện toàn bộ
Shoreline and coral reef ecosystem changes in gulf of Mannar, Southeast coast of India
Journal of the Indian Society of Remote Sensing - Tập 31 - Trang 157-173 - 2003
M. Thanikachalam, S. Ramachandran
Changes in shoreline, coral reef and seafloor have been mapped using remote sensing satellite data of IRS LISS-III (1998), IRS LISS-II (1988), Survey of India Topographic sheet (1969), Naval Hydrographic Chart (NHO) 1975 and bathymetry data (1999) with ARC-INFO and ARC-VIEW GIS. The analysis of multi-date shoreline maps showed that 4.34 and 23.49 km2 of the mainland coast and 4.14 and 3.31 km2 are... hiện toàn bộ

Application of Remote Sensing in Monitoring Unsustainable Wetlands: Case Study Hamun Wetland
Journal of the Indian Society of Remote Sensing - Tập 46 - Trang 1871-1879 - 2018
Saeideh Maleki, Alireza Soffianian, Saeid Soltani Koupaei, Sassan Saatchi, Saeid Pourmanafi
Monitoring wetland as one of the important parts of the global ecosystem is necessary for conservational programs. But, usually, collecting in situ data is restricted in these areas because of their remote locations, vast area and dynamic conditions. Remote sensing provides a cost effective tool to investigate hydrological patterns and the seasonal trend of changes in wetlands. In this paper, Land... hiện toàn bộ
