Removal of Thin Clouds in Landsat-8 OLI Data with Independent Component Analysis
Shen, Yang; Wang, Yong; Lv, Haitao; Qian, Jiang (2015)An approach to remove clouds in Landsat-8 operational land imager (OLI) data was developed with independent component analysis (ICA). Within cloud-covered areas, histograms were derived to quantify changes of the reflectance ... -
A Sparsity-Based InSAR Phase Denoising Algorithm Using Nonlocal Wavelet Shrinkage
Fang, Dongsheng; Lv, Xiaolei; Wang, Yong; Lin, Xue; Qian, Jiang (2016-10-10)An interferometric synthetic aperture radar (InSAR) phase denoising algorithm using the local sparsity of wavelet coefficients and nonlocal similarity of grouped blocks was developed. From the Bayesian perspective, the ...
