The problem with these: Every half a year we hear about new revolutionary image transformation. Today it's super-resolution, last year it was low-res PC games graphics interpolation, year before that - filter that could resize images by one direction (e.g. width) while preserving proportions and throwing away less interesting parts. The image will become 2x narrower and you'll hardly notice.

Sadly, this is usually first and last time we see the technology in question. They do not seem to produce any impact that could increase our quality of life. They just sit on some dusty shelves somewhere.




That's hardly the case.

The low-res texture stuff is widely used in emulators (both mobile and on PCs) - after all, that's exactly where it was meant to be used.

The seam carving (the "least interesting line removal" thing) is now a major feature of Photoshop (called content-aware scale) and has become really well integrated (I hear there are attempts to do in video as well).

The fact that you don't see this tech in your line of work doesn't mean it's not out there.


Glad to hear seam carving took off. It looked like the most amazing thing when it was introduced.


Do you have sources for each those, especially the uni-directional resizing? They sound quite interesting.


The technique is called Seam Carving: https://en.wikipedia.org/wiki/Seam_carving

It effectively eliminates the least interesting line when performing a resize, allowing you, for example, to resize a skyline by eliminating the uninteresting smaller buildings and gaps.


There's even an iOS app called Liquid Scale that will do this right on your iPhone.

There may be others but I haven't run across them.


They are usable implementations of all these graphic algos. See: http://www.scriptol.com/programming/graphic-algorithms.php
