UNMIXING-BASED DENOISING AS A PRE-PROCESSING STEP FOR CORAL REEF ANALYSIS
Hyperspectral remote sensing Coral Denoising Water Derivative Features Spectral Unmixing
2017/7/12
Coral reefs, among the world’s most biodiverse and productive submerged habitats, have faced several mass bleaching events due to climate change during the past 35 years. In the course of this century...
CUBESAT-DERIVED DETECTION OF SEAGRASSES USING PLANET IMAGERY FOLLOWING UNMIXING-BASED DENOISING: IS SMALL THE NEXT BIG?
Mediterranean seagrass Posidonia oceanica Planet CubeSats Unmixing-based denoising Depth-invariant index Support Vector Machines
2017/7/12
Seagrasses are one of the most productive and widespread yet threatened coastal ecosystems on Earth. Despite their importance, they are declining due to various threats, which are mainly anthropogenic...
DENOISING ALGORITHM FOR THE PIXEL-RESPONSE NON-UNIFORMITY CORRECTION OF A SCIENTIFIC CMOS UNDER LOW LIGHT CONDITIONS
CMOS Denoising algorithm Pixel-response non-uniformity
2016/7/28
We present a denoising algorithm for the pixel-response non-uniformity correction of a scientific complementary metal–oxide–semiconductor (CMOS) image sensor, which captures images under extremely low...
EVALUATION OF WAVELET AND NON-LOCAL MEAN DENOISING OF TERRESTRIAL LASER SCANNING DATA FOR SMALL-SCALE JOINT ROUGHNESS ESTIMATION
terrestrial laser scanning range noise data resolution joint roughness wavelet transform non-local mean denoising performance
2016/7/27
Terrestrial Laser Scanning (TLS) is a well-known remote sensing tool that enables precise 3D acquisition of surface morphology from distances of a few meters to a few kilometres. The morphological rep...

New SAR Interferogram denoising method via sparse recovery based on L0 norm
Interferogram filtering phase estimation sparse coding l0 minimization approximate message passing
2014/9/29
The goal of this paper is to estimate a denoised phase image from the observed noisy SAR interferogram. We proposed a linear model to obtain a sparse representation of the interferomteric phase image....
Image matching techniques can nowadays provide very dense point clouds and they are often considered a valid alternative to LiDAR point cloud. However, photogrammetric point clouds are often character...
CURVELET APPROACH FOR SAR IMAGE DENOISING, STRUCTURE ENHANCEMENT, AND CHANGE DETECTION
SAR Imagery Structure Extraction Change Detection Method Urban
2016/3/1
In this paper we present an alternative method for SAR image denoising, structure enhancement, and change detection based on the
curvelet transform. Curvelets can be denoted as a two dimensional furt...
