Ostagram
Ostagram blends a photo you upload with the artistic style of a second reference image using neural style transfer. You pick a content photo and a style source, then the site runs a convolutional network based on the Gatys artistic style algorithm described on its About page. Results land in a public feed where you can browse day, week, month, and year leaderboards while long jobs finish.
Phone filter apps slap one-click presets on your shots. Ostagram instead merges two specific images so you control both the scene and the painter or texture you imitate, which is closer to classic style transfer research than a generic art filter. The trade-off is wait time: the About page estimates about 1.5 to 2 hours of processing on an average home computer, so you browse the gallery instead of staring at a progress bar.
Hobbyist designers, digital artists, and photo experimenters who want painterly remixes without manual brushwork are the natural audience. English and Chinese language options on the feed navigation suit a global community posting to the shared gallery.

How does Ostagram work?
Ostagram applies neural style transfer to blend your uploaded photo with a style image you choose. The About page describes convolutional networks using the Gatys artistic style algorithm to paint a new image.
How long does Ostagram processing take?
Ostagram estimates about 1.5 to 2 hours on an average home computer. The About page advises browsing the gallery while processing runs instead of waiting on the page.
Do I need an Ostagram account?
Yes, Ostagram requires registration before uploading pictures. The About page states sign-up is required for uploads, with English and Chinese locale options on the site.
What can I do on the Ostagram feed?
Ostagram hosts a gallery of community style transfers you can browse. Feed navigation sorts top works by day, week, month, year, and all-time best lists.
What technology powers Ostagram?
Ostagram uses convolutional neural networks for artistic style transfer. The About page cites the Gatys, Ecker, and Bethge algorithm and links to an official GitHub implementation.
Which languages does Ostagram support?
Ostagram offers English and Chinese locales. The gallery navigation includes EN and CN switches on the public feed pages.
