Image Preservation - Experiment Two

A second pass and more thought out approach. Original 260 X 128 image:

Original

2X Enlarged

Original

Median Filter

Original

Sharpen

Original

2X Enlarge. Now it's a 4K image.

Original

Clarify.

Original

Sharpen more.

Original

Edge preserving smooth.

Original

Resize by 50% to take it back down to a 2K image.

Not only will it work now (albeit badly) at 2K - 4K resolutions, but it also looks good at the original resolution and even works just fine and 2x - 3X original size.

Here's what happens when you zoom them right up. You have to scale the original 260 pixel wide image but now you have a 2000 pixel wide version as well and can use that where in image needs to be used but it not in the approprotate size.

It's true it would be nice if it were sharper but this is still not bad considering the 260 pixel wide source.
