Visualization method for SAR images based on a negative exponential transformation and mean-shift algorithm
Jian Yang · Journal of Tsinghua University(Science and Technology) · 2011
A visualization method was developed for synthetic aperture radar(SAR) images to facilitate visual interpretation of SAR images.A negative exponential transformation is performed on the original SAR image with the transform parameter then modified based on the mode of the output image histogram which estimated by the mean-shift algorithm.The original image is then re-transformed using the modified parameter.Test results show that this method appropriately stretches the dark pixels while the bright details are preserved.The robustness of this method is demonstrated using SAR images of various scenes.
