Hilbert's curve
WebOct 31, 2024 · Hilbert Curves is a unique app authored and illustrated by Doug McKenna in the form of a book that shows, explains, and lets you explore and play with, you guessed it, Hilbert curves. WebMay 23, 2024 · The Hilbert curve is a space filling curve that visits every point in a square grid with a size of 2×2, 4×4, 8×8, 16×16, or any other power of 2. It was first described by David Hilbert in 1892. Applications of the Hilbert curve are in image processing: especially image compression and dithering.

WebNov 28, 2016 · At the n th level, we see that the square is broken into 4 n subsquares and the polygonal approximation to the ultimate space-filling curve consists of 4 n − 1 segments of length 1 / 2 n. Thus, the length of the approximating curve at stage n is ( 4 n − 1) / 2 n. This same approach can be used to find the length of the three-dimensional ...

WebOct 30, 2024 · Further, an object in 3D space, expressed by a 3D Hilbert curve, could be expanded to 2D space, and the neighboring properties of spatially adjacent voxels would be maintained on the 2D image (Fig. 3c). Therefore, in image analysis, with the help of a 3D Hilbert curve, current intra-tumoral heterogeneity analysis techniques could be employed … WebThe curve X0(N) = Γ0(N)\H, can be given as a plane curve by the modular polynomial Φ n(X,Y). These can quickly get very complicated. For instance, for N= 2 we have Φ2(X,Y) = …
The Hilbert curve (also known as the Hilbert space-filling curve) is a continuous fractal space-filling curve first described by the German mathematician David Hilbert in 1891, as a variant of the space-filling Peano curves discovered by Giuseppe Peano in 1890.
