Hi Raoul,

I read the article, and have some comments...

The original image showed Titan 8 pixels across, and that's all the real information in this image (technically, it contains 8pixels X 8pixels X 24bits-per-pixel = 1,536 bits of information).

He's enlarged the image a lot, using an interpolation technique that synthesizes additional pixels. He probably also sharpened the image after enlargement. There's no more information in the image after processing--the additional detail you think you see is artificial. I'd state this "law" as: "Information in an image may be destroyed, but it may not be created through post-processing." Something like conservation of energy...

That doesn't mean that the image is necessarily wrong, though its accuracy may be a fortuitous accident. Enlargement by interpolation is based on the assumption that if two adjacent pixels have very different brightness, the underlying reality is that there's a smooth gradient of brightness between the center of one pixel and the center of the next. So, if you "move" the two pixels apart by enlargement, you can legitimately add pixels between them that transition smoothly from the brightness of one to the brightness of the other. In the real world, that's often the correct thing to do.

But, of course, sometimes that assumption is incorrect. In this case, the images from other instruments seem to validate the assumption. Nevertheless, though it's a good-looking image, I have to credit its creator more with good luck than developing a new image processing technique.

(I may be rambling, due to a case of the flu that has my head feeling like it's wrapped in cotton. Sorry about that...)
