Viewed planets with a cute camcorder, and mucked around with processing the images. Basically finding the relative positions and drawing them ontop of each other. Probably not a great method per-see. See here for some reasoning.. But havent figured something that does more than making using the power of programming to make a vague picture from a pixelated movie.
In the table:
| movie: | part of the video actually containing the planet. |
| gpo: | "given" position overlay. Uses the average pixel position. |
| mto: | match-template overlay. Uses the best match on the gpo to (perhaps) find the location better. |
| pdgpo_max: | basically used gpo twice. And draws-again with brightnesses based on actual pixels and bot actually drawing a "block" of each pixel, but instead re-draws the original image assuming that is actually responsible.(pretty ad-hoc) |
| mto_mulav, gpo_mulav: | Actually the same as gpo and mto regular, but "multiplicative average", but taking the logarithm first and then exponentialling them. (code>a*b = exp(log(a) + log(b))) |
The adorable camcorder responsible:
