WitrynaFor instance, ratioing multi-temporal SAR images and logarithmic scaling of the ratio-image are two stages used to obtain the difference image in the literature (Dekker, 1998 ). The ratio operator represented in the logarithmic scale is used to compare the multi-temporal SAR images (Bazi, Bruzzone, & Melgani, 2005 ).
