A Framework for Statistical Nonlocal Means Noise Reduction in PolSAR Data

Fully Polarimetric SAR (Synthetic Aperture Radar), PolSAR, inherits the advantages of SAR systems (day and night imaging capacity, almost all-weather and active imaging), while extending its capabilities through the use of four polarization combinations (Horizontal and Vertical - HH, VV, HV, VH) [1]. PolSAR data integrates multiple types of rich information, such as frequency, amplitude and phase, which contributes to better characterizing different targets.
