Analyzing image using Hilbert-curve

问题:

I would like to visit each pixel of an image using the "path" of the Hilbert-curve. I've found a recursive implementation of the Hilbert-cuve here, but I don't know how to apply this on an image. Is it important to have a picture which width and height are equal?

回答1:

No, but make sure the curve is adaptive or is bigger than the image. Adaptive curve is very complicated.
