Two Weeks of Colorizebot
- mattip 10y agoCool idea nicely executed and documented. Their other posts are worth a look too.
- ivoras 10y agoI feel that things like this are very important to create and have, even if they may not be easily made commercial. It's like pure science within IT. Very cool!
- truth_sentinell 10y agoI am astonished by this because I don't get how it can paint based on an algorithm and get everything so right. How does this even work? How it know metal is metal and what color to use? Does it paint black people as white?
- roywiggins 10y agoAt a guess, it's looking at texture and shape. There's a lot of information in texture. Stuff that looks like skin gets pink or sepia Stuff that looks like grass gets green Stuff that looks like sky gets blue Stuff that looks like fabric gets red or blue Stuff it's not sure about gets sepia Very cool to see it done automatically. It's about the level of a mediocre human colorizer which isn't bad for an algorithm...
- truth_sentinell 10y agoCould you refer me where I could learn these analyzing algorithms? And where to code bots overall. I have some pretty cool ideas and the internet is an infinite playground to throw bots in, lay back and get you results.

- joakleaf 10y agoWould be fun to see an entire B/W movie processed...
- maaaats 10y agoThey did show some example-videos in the article. From the Beatles-video, this looks quite a few steps away from working well. When they change camera, walls etc. suddenly changes colors, as the images are processed separately.
- joakleaf 10y agoSorry. Didn't notice. Yes, the videos are not as impressive as the stills.
- vanderZwan 10y agoWould it be require a lot of changes to repeat the training process mentioned in the article with video instead of stills? Aside from the increase in data being processed.
- abricot 10y agoSchindler's list with all-pink nazi uniforms...
- byuu 10y agoHalf-joking, half-serious, but ... how long before someone writes a YCbCr 4:0:0 video encoder that uses colorizebot on the resulting frames? Obvious use case being absolutely extreme video compression at substantial color accuracy loss. Or is this algorithm hopelessly below the threshold for real-time usage? That, and I imagine there'd need to be some strong multi-frame averaging if the colors shift too greatly between individual frames that are mostly identical in the original material. EDIT: ah, videos at the bottom, yay! But yeah, serious color shifting issues, darn. So if this is to work at all, it'd need some color stabilization. https://www.youtube.com/watch?v=tWdaMKKH5MI https://www.youtube.com/watch?v=tWdaMKKH5MI
- andromeduck 10y agoSeems like it should be combined with hints from calculating optimal flow on previous frames.
- stesch 10y agoAnd popular subreddits like /r/pics have banned the bot. :-(
- ap22213 10y agoA lot of the colorizations seem really poor. They don't even look lifelike. What are the technical reasons why some of the 'old' b/w photos seems much more realistic than the others? Is it the type of film or processing that were used in creation of the originals?
