Scaling Analysis of Ocean Surface Turbulent Heterogeneities from Satellite Remote Sensing: Use of 2D Structure Functions - Fig 3

<p><b>A) Simulation of 2D fractional Brownian motion for various Hurst exponents (<i>H</i> = 0.1, 0.2.., 0.9).</b> The white rectangles are the space where the data have been removed to test this method for deriving <i>H</i> using spatial Structure function method. The 2D structure function was applied to each full image and also to the same image with white rectangles removed, in order to show that this scaling method can be applied to irregular images. B) For each image, comparison of the <i>H</i> value estimated using the structure function for the full image and for images with missing values.
