Latent walk

A decoder is defined everywhere in its code plane, not only at the codes of stored pictures.

Question: If you walk in a straight line from one code to another, what does the decoder give you in between?

Schematic Schematic: the decoder is a two-number rule written for this lab, not a trained network. The frames walk the code from A (-0.80, -0.80) to B (0.80, 0.80) through 11 of the 21 computed stops; the midpoint code (0.00, 0.00) gives a circle of radii 2.20 by 2.20, centred (8.0, 8.0) cells, with light 13.5 against 10.1 at either end, and the largest pixel change between neighbouring stops is 0.486. All 21 pictures are computed exactly by data/scripts/c22.s03.L1.py; nothing is measured and nothing is randomly drawn.

Lab controls

walk position t, where the film starts0.5

Left/Down and Right/Up move one stop of 0.10; Page Up/Down also move one stop; Home sets 0.00; End sets 1.00. Choosing a stop starts the film there.

Frame 1 of 6: t 0.50, a circle at the midpointThe midpoint: code (0.00, 0.00), radii 2.20 by 2.20, centre (8.0, 8.0), light 13.5. It is a circle, not a blend of A and B: the light is 1.34 times the 10.1 at either end, because the two radii trade one for the other.

Keyboard: Space plays or pauses, Left and Right step, Home goes to the first frame, End goes to the last frame.

Text description of this lab

A square code plane holds two codes, A at the upper left and B at the lower right, joined by a straight navy line with a gold marker that slides along it. Beside the plane a 16 by 16 grey picture changes without a break: a tall pale ellipse at A becomes a circle at the midpoint, then a wide ellipse at B. A strip of 21 small thumbnails shows every stop.
