Smooth SCAD: A Raised Cosine SCAD Type Thresholding Rule for Wavelet Denoising
Radhika Kulkarni, Aluisio Pinheiro, Brani Vidakovic +1
We introduce a smooth variant of the SCAD thresholding rule for wavelet denoising by replacing its piecewise linear transition with a raised cosine. The resulting shrinkage functio…
Wavelet-based estimation of power densities of size-biased data
Michel H. Montoril, Aluísio Pinheiro, Brani Vidakovic
We propose a new wavelet-based method for density estimation when the data are size-biased. More specifically, we consider a power of the density of interest, where this power exce…
Wavelet Spatio-Temporal Change Detection on multi-temporal PolSAR images
Rodney Fonseca, Aluísio Pinheiro, Abdourrahmane Atto
We introduce WECS (Wavelet Energies Correlation Sreening), an unsupervised sparse procedure to detect spatio-temporal change points on multi-temporal SAR (POLSAR) images or even on…
Nonparametric methods for detecting change in Multitemporal SAR/PolSAR Satellite Data
Rodney Fonseca, Guilherme Ludwig, Michel Montoril +1
We employ nonparametric statistical procedures to analyse multitemporal SAR/PolSAR satellite images. The aim is two-fold. We seek parsimony in data representation as well as effici…
