photomosaic

I just got back from a vacation with family. My sister had this idea to assign everyone a color to take pictures of as we walked around. Not everyone was enthused about the itinerary for the day, and this turned out to be a brilliant way to keep everyone engaged, and to feel like we were all contributing to something fun together. At the end, we uploaded them to a shared Apple Photos album and she’s going to arrange them into a collage. So, I love this idea! I think it would be great if there were a way for an arbitrary number of people to participate in versus mode, but in the end, have the option to combine the results into one big block. It would also be super cool for a group to contribute to a photo mosaic: https://github.com/worldveil/photomosaic e.g. a family photo composed from the photos we took.

Tile images, set randomness, build videos with tile images, and do face alignment montages with embedding network: https://github.com/worldveil/photomosaic

yep. https://github.com/worldveil/photomosaic

Is the example image (https://github.com/worldveil/photomosaic/blob/master/media/r...) with or without opacity cheat?

It's using the KMeans[1] library from sklearn.cluster. But this isn't really ML, is it? My ML knowledge is limited. Regardless, it's a cool project. OP might want to update the title to remove ML. [1] https://github.com/worldveil/photomosaic/blob/master/emosaic...

I'm not an expert in the topic, but my understanding is RGB is a poor color space for computing color difference. This could be why your mosaics end up so washed out. [1] suggests using a CIELAB color space [2]. Edit: Looking at the code more closely it looks like you were using Lab at one point but commented it out[3], so I'm guessing you're already aware of this. 1: https://stackoverflow.com/a/9019461/185171 2: https://en.wikipedia.org/wiki/CIELAB_color_space#CIELAB 3: https://github.com/worldveil/photomosaic/blob/bb720efda11383...
