Two-Stream Convolutional Networks for Dynamic Texture Synthesis

Requirements

• Tensorflow 1.3 (or latest, although not tested)
• Preferably a Titan X for synthesizing 12 frames
• Appearance-stream tfmodel
• Dynamics-stream tfmodel
• Dynamic textures
• Static textures (for dynamics style transfer)

Setup

1. Store the appearance-stream tfmodel in ./models.
2. Store the dynamics-stream tfmodel in ./models. The filepath to this model is your --dynamics_model path.

Dynamic texture synthesis

python synthesize.py --type=dts --gpu=<NUMBER> --runid=<NAME> --dynamics_target=data/dynamic_textures/<FOLDER> --dynamics_model=models/<TFMODEL>

Store your chosen dynamic texture image sequence in a folder in /data/dynamic_textures. This folder is your --dynamics_target path.

Example usage

python synthesize.py --type=dts --gpu=0 --runid="my_cool_fish" --dynamics_target=data/dynamic_textures/fish --dynamics_model=models/MSOEnet_ucf101train01_6e-4_allaug_exceptscale_randorder.tfmodel

Dynamics style transfer

python synthesize.py --type=dst --gpu=<NUMBER> --runid=<NAME> --dynamics_target=data/dynamic_textures/<FOLDER> --dynamics_model=models/<TFMODEL> --appearance_target=data/textures/<IMAGE>

Store your chosen static texture in ./data/textures. The filepath to this texture is your --appearance_target path.

Example usage

python synthesize.py --type=dst --gpu=0 --runid="whoa_water!" --dynamics_target=data/dynamic_textures/water_4 --appearance_target=data/textures/water_paint_cropped.jpeg --dynamics_model=models/MSOEnet_ucf101train01_6e-4_allaug_exceptscale_randorder.tfmodel

Temporally-endless dynamic texture synthesis

python synthesize.py --type=inf --gpu=<NUMBER> --runid=<NAME> --dynamics_target=data/dynamic_textures/<FOLDER> --dynamics_model=models/<TFMODEL>

Incremental dynamic texture synthesis

python synthesize.py --type=inc --gpu=<NUMBER> --runid=<NAME> --dynamics_target=data/dynamic_textures/<FOLDER> --dynamics_model=models/<TFMODEL> --appearance_target=data/textures/<IMAGE>

Store your chosen static texture in /data/textures. The filepath to this texture is your --appearance_target path. This texture should be the last frame of a previously generated sequence.

Static texture synthesis

python synthesize.py --type=sta --gpu=<NUMBER> --runid=<NAME> --appearance_target=data/textures/<IMAGE>

Gatys et al.'s method of texture synthesis.

Notes

The network's output is saved at data/out/<RUNID>.

Use ./useful_scripts/makegif.sh to create a gif from a folder of images, e.g.,

./useful_scripts/makegif.sh "data/out/calm_water/iter_6000*" calm_water.gif

will create the gif calm_water.gif from the images iter_6000* in the calm_water output folder.

Logs and snapshots are created and stored in ./logs/<RUNID> and ./snapshots/<RUNID>, respectively. You can view the loss progress for a particular run in Tensorboard.
