# ee.Image.rsedTransform

Reverse Squared Euclidean Distance (RSED) computes the 2D maximal height surface created by placing an inverted parabola over each non-zero pixel of the input image, where the pixel's value is the height of the parabola. Viewed as a binary image (zero/not-zero) this is equivalent to buffering each non-zero input pixel by the square root of its value, in pixels.
