↑ Rainbow ripples of the distance transform — split a coin photo into black and white, then paint “how many pixels from the edge?” in rainbow colors, and ripple-like contour lines emerge. Ops used: otsu, fill_up, distance_transform.
↑ The Fourier world — view an image in frequency space, and “what fineness of pattern, in what direction” becomes points of light. A regular weave glows like a constellation (the weave panel only is synthetic). Op used: fft_image.
↑ Watershed’s coloring-book segmentation — mimic water flowing downhill and pooling, and each coin gets its own color. Ops used: otsu, distance_transform, watersheds, colorize_labels.
↑ The edge compass — paint contour direction with the colors of a hue wheel, and lines pointing the same way glow the same color. Ops used: sobel_amp, sobel_dir.
↑ Six universes born from simple rules — from nothing more than “look at your neighbors and decide your own color” come fractals, chaos, sandpile mandalas, dendrites, and coral patterns (simulation imagery). Ops used: alife_wolfram1d, alife_sandpile, alife_dla, alife_lenia, alife_cyclic_ca.
↑ An X-ray photograph of a Triceratops — pack the Smithsonian’s real skeleton scan (CC0) into voxels and take a maximum-intensity projection (MIP), and it comes out looking just like an X-ray. Ribs and horns both show. Ops used: voxelize, vol_gaussian, vol_mip.
↑ A dragon that pops out with red-blue glasses — the real Stanford dragon scan rendered from 2 viewpoints and overlaid in red-cyan as an anaglyph. Put on red-blue glasses and it floats. Ops used: read_mesh, look_at, render_mesh.
↑ The Triceratops mountain range — turn the skeleton into a 600,000-point cloud and build an elevation map from directly above, and the spine becomes a mountain range, the ribs its ridgelines. The same ops a robot uses to read terrain. Ops used: sample_surface, elevation_map, colorize_height.
↑ Shapes growing and shrinking — coins puff up and merge under dilation, then slim down under erosion. Fundamental ops used in factory image inspection too. Ops used: dilation_circle, erosion_circle.
↑ Space gone wobbly — imagine an invisible rubber sheet under the image, then pinch and pull it in three different styles: TPS / FFD / MLS. Ops used: deform_tps, deform_ffd, deform_mls.
↑ Extracting a skeleton from a dinosaur silhouette — the centerline (skeleton) of a Triceratops skeleton’s shadow, extracted at 1-pixel width. Legs, horns, and tail remain like wirework. Ops used: sk_skeleton, distance_transform, and others.
