Data
The traing and testing data can be downloaded from: https://drive.google.com/drive/folders/1bmJREP58WNvq9o5nIwNQEEce7cb3uEDk?usp=sharing
- "data/orgTrainingImages" contians the original 512x512 training images rendered using mitsuba.
- "data/train" contains the cropped 128x128 training patches we use for joint training and refinement.
- "data/test" contains the testing dataset rendered using mitsuba.
- "data/real" contains the real data we captured at UC San Diego.
- "shapes" contains the procedually generated shapes, we created to render the dataset.
- "trained/dirs" contains our learnt optimal light directions for different settings.
- "trained/joint" contains our trained networks of different training settings after jointly training.
- "trained/refine" contains our trained networks of different training settings after refining the Relight Net.
- "env" contains a testing environment map.
Platform
This code is based on python 2.7 with tensorflow 1.3.0. It has been tested on Ubuntu 16.04.
Usage
- To train the Sample Net and Relight Net jointly with a setting of 90 degree cone and 5 samples. Run:
python run_train_joint.py 90 5 -i ../data/train/joint_npy -o OUTFOLDER
- To refine training a Relight Net with our cropped data. Run:
python run_train_refine.py 90 5 -i ../data/train -o OUTFOLDER -j ../trained/joint -d ../trained/dirs
- To test a trained Relight Net on our testing dataset. Run:
python run_test.py 90 5 -i ../data/test/mapper_100_sameDir -o OUTFOLDER -w ../trained/refine -d ../trained/dirs
- To test a trained Relight Net on one of our real data. Run:
python run_test.py 90 5 -i ../data/real/0 -o OUTFOLDER -w ../trained/refine -d ../trained/dirs
- To render one data under a environment map. Run:
python run_renderEnv.py 90 5 -i ../data/real/0 -o OUTFOLDER -w ../trained/refine -d ../trained/dirs
- To play with creating new shapes. Run:
python run_genShapes.py -o OUTFOLDER
