I don't want to see what would look like if seam carving was applied to it
Woah, I didn't know about those first two algorithms. The first one, Waifu2x, looks especially nice. Something I always wondered, though, is if there is a tool that can bulk resize an entire sprite sheet or a bunch of images rather than one by one. That could be handy for pixel art resizing because resizing an entire sprite sheet causes each sprite to bleed on the corners of the one next to it.
for f in $(find . -type f); do./waifu2x-converter-cpp -i $f; done
I still have my source code, maybe I should run Walrii through it?
Oh noes D:. But yeah this algorithm probably works best with people photos with the right coloring/gamma/contrast, right?
Hey @VMike,as you may have noticed when using Waifu2x, it is very CPU-intensive !My AMD FX 6300 can take up to 2 minutes to upscale to a 2k image, let alone for 4k...For real-time upscaling, it needs to be much faster than that, at least 30 images per second.The only way for it to be practical way would be to make use of GPU acceleration (via CUDA or OpenCL) but even then,it would require a powerful GPU (at least a Titan), fast storage (Samsung SSD), fast DDR4 memory etc...Not impossible but very impractical for most people.Also, Waifu2x would be best suited for visual games and games with anime-styled graphics.Resident Evil looks interesting with Waifu2x, almost like a painting.But for now, it's best suited for still pictures and maybe movies (if you are doing frame-by-frame).
