Is it possible to apply the Otsu thresholding (or any other image processing algorithm dedicated to image digital values in the interval [0, 255]) to a Radiometrically calibrated Sentinel-1 SAR product for which the pixel values (sigma0) are signed real (negative or positive decimal) and are not normalized (logarithmic scale)?
If it's feasible, how should the intensity values be rescaled to the byte interval ([0, 255]) prior to the processing?
