Interactive imagesOne embedding, band by band
One embedding, band by band
The values of one pixel's embedding as bars, each band as a map, and the window drawn from any three bands.
Point at any pixel to read its embedding as bars, point at a bar to see its band alone, or draw the window from any three bands.

Move over the image to read a pixel, click to keep it. Point at a bar to see its band alone.
What to try
- Cross a boundary. Move the pointer over the image, from a field into the vegetation next to it. Inside a field the bars barely move; at its edge the whole profile changes shape.
- Look at one band alone. Point at any bar, or focus the bars and walk along them with the arrow keys: the image shows that band alone, in grey. Which bands tell the fields from the vegetation around them, and which tell fields from each other? No band has a name, so looking is the only way to find out.
- Change the colours, not the picture. Press Surprise me a few times. The colours change completely and the shapes do not: what separates one place from the next is in the vectors.
- Make a grey image from three menus. Set R, G and B to the same band. The image is then that band alone, as a bar shows it.
- Read the bars that are cut. The axis of the bars is fixed, so that two pixels can be compared. A bar that would pass it ends in a small point; point at it to read its true value.
