3D Hilbert Compression: Results

Monday 22 March, 2010 · Thesis

Last week I had a working implementation of the n-dimensional Hilbert algorithm. Next step was using a 3D Hilbert curve on my depth maps. Goal: further increase the compression ratio of my depth maps. I had already done some tests with this kind of curve two weeks ago and back then the results were interesting [...]

In my attempt to find out why the Hilbert curve doesn’t give better results than the Zig-Zag one, I experimented a bit with rotated versions of my path-filling curves. Instead of going from left to right, I tried going up and down (= 90° rotation). A 2D representation of this: Original Zig-Zag (left) and the [...]

256 depth maps, 32 samples per pixel. Stanford Bunny Uncompressed Stanford Bunny Compressed Red areas indicate difference with the uncompressed version. In general I have less noise/self-shadowing, but some trivial points on the bunny are now miscalculated. It might have something to do with a special case where my current implementation of the compression algorithm [...]
