Upscaling / Enlarging
Thanks to fellow “XnThusiast” cday, I learned about a freeware program the other day that promises better image scaling quality and can upscale and enlarge photos better than Photoshop's “Preserve Details” algorithm: Steffen Gerlach's “A Sharper Scaling is a high quality image scaling technology mainly developed for upscaling.”

Re: Upscaling / Enlarging
Upscaling icons, drawings
http://waifu2x.me/
It's a on-line utility , upscaling up to 10x10, using Deep Convolutional Neural Networks
(it's a bit slow, so test with small pictures)
Original picture
Zoom in
Classic soft
Using Waifu
You can also clean photos for jpeg artefacts : (style: photo, magnification :0 , noise reduction high)

Re: Upscaling / Enlarging
Thank you for the examples, michel038
cday had brought waifu2x to my attention last year when it was first released to the public, but at the time I failed to realize that its potential uses go beyond anime-style art.

- Depixelizing Pixel Art
Naïve upsampling of pixel art images leads to unsatisfactory results. Our algorithm extracts a smooth, resolution-independent vector representation from the image which is suitable for high-resolution display devices.- Pixenlarge
Pixenlarge is an image enlargement tool. It is distributed both as a plug in for Adobe Photoshop and also as a standalone application. It is mainly specialized in enlarging drawn images, such as e.g. clip arts, icons, drawings, sketches, cartoons etc.- Scale2x
Scale2x is real-time graphics effect able to increase the size of small bitmaps guessing the missing pixels without blurring the images.

Re: Upscaling / Enlarging
Two more good ones (both free )
http://www.fitswork.de/software/softw_en.php
http://cas.eedept.kobe-u.ac.jp/WelcomeE ... ex_en.html
SAR's PseudoLAD is my fav though.
PS: And this for pixel art: https://sourceforge.net/projects/xbrz/ (Get ScalerTest app)

Re: Upscaling / Enlarging
Anime4K, FSRCNNX and NIS would also be good

Re: Upscaling / Enlarging
FSR 2.0 which is open source, can also be used to upscale still images, besides renders... command line only for now:
