This paper focuses on the evaluation and analysis of seven frequently used image fusion quality assessment methods to see whether, or not, they can provide convincing image quality or similarity measurements. The seven indexes are Mean Bias (MB), Variance Difference (VD), Standard Deviation Difference (SDD), Correlation Coefficient (CC), Spectral Angle Mapper (SAM), Relative Dimensionless Globa...

The potentials of the forthcoming new European Space Agency‘s (ESA) satellite sensor, Sentinel-2, for archaeological studies was examined in this paper. For this reason, an extensive spectral library of crop marks, acquired through numerous spectroradiometric campaigns, which are related with buried archaeological remains, has been resampled to the spectral characteristics of Sentinel-2. In add...

An ultra-broadband graphene-gold film saturable absorber mirror (GG-SAM) with a spectral coverage exceeding 1300 nm is experimentally demonstrated for mode-locking of bulk solid-state lasers. Owing to the p-type doping effect caused by graphene-gold film interaction, the graphene on gold-film substrate shows a remarkably lower light absorption relative to pristine graphene, which is very helpfu...

The mapping of hydrothermal alteration zones associated with epithermal gold deposits on the island of Lesvos in Greece has been carried out using Landsat Thematic Mapper (TM) satellite and ground remote sensing data. The initial analysis of the satellite data using the minimum noise fraction, matched filter and spectral unmixing techniques identified the altered rock outcrops clearly. The iden...

Target detection is one of research focuses for precision chemical application. This study developed a method to identify seedling cabbages and weeds using hyperspectral imaging. In processing the image data with ENVI software, after dimension reduction, noise reduction, de-correlation for high-dimensional data, and selection of the region of interest, the SAM (Spectral Angle Mapping) model was...

The assessment of changes in forest coverage is crucial for managing protected areas, particularly the face climate change. This study monitored cover dynamics a 6535 ha mountain area located north-west Romania as part Apuseni Natural Park from 2003 to 2019. Two approaches were used: vectorization orthophotos and Google Earth images (in 2003, 2005, 2009, 2012, 2014, 2016, 2017, 2019) satellite ...

Riparian forests are critical for carbon storage, biodiversity, and river water quality. There has been an increasing use of very-high-spatial-resolution (VHR) unmanned aircraft systems (UAS)-based remote sensing riparian forest mapping. However, improved forest/zone monitoring, restoration, management, enhanced understanding the accuracy different classification methods mapping other land cove...

A known target detection assumes that the to be detected is provided a priori , while an anomaly unknown without any prior knowledge. As a result, generally performs search-before-detect in active mode, referred as opposed which throw-before-detect passive detection. Accordingly, techniques des...

Introduction: Since January 2004, OMEGA/Mars Express data has revealed a diverse and complex Martian surface mineralogy [1]. The important findings, together with Thermal Emission Spectrometer (TES), Thermal Emission Imaging System (THEMIS), and insitu observations from Mars Exploration Rovers, include but not limited to (1) hydrated sulfates [1, 2, 3, 4, 5, 6, 7]; (2) iron oxides and oxhydroxi...
