Deepdream for any size image.
I got annoyed with artists keeping their any-sized deep dream code closed source, and making a big deal about it.
So made my own in a few hours - peow!
Make sure you have caffe installed and it's python modules in your PYTHONPATH
pip install -r requirements
python tiled_dreamer.py -i my_large_input.jpg -o my_large_output.jpg -t inception_4e/3x3
Also of interest might be the --explore option, which will iterate through the layers
and try dreaming on each (while filtering our the dummy "split" layers Caffe creates).
To deepdream at any size:
- split into tiles, but overlap the tiles by N pixels(here N is hardcoded to 32), this ensures the edge pixels have the required context
- jitter each tile in the same direction. This means saving the jitter of the first tiled moving all tiles by the same amount.
- combine the tiles, by discarding the edges (half of the overlap amount), also deal with boundary conditions
- when you move up an octave, split into new tile sizes.
Fucking Apache because code adapted from the original deep dream ipython notebook
