SAR Image Processing: Non-Statistical, Statistical, and Frequency-Domain Filtering Methods

Non-statistical filtering methods: Mean Filter, Median Filter, K-Nearest Neighbors Filter; Statistical filtering methods: Lee Local Statistics Filter, Maximum A Posteriori Filter; Frequency-domain approach primarily utilizes wavelet transform, notably the wavelet soft-thresholding method proposed by D.L. Doholo et al.
