This repository contains the demo code for SIGNET: Efficient Neural Representations for Light Fields, published at ICCV 2021. We provide the Python implementation of Gegenbauer embedding as well as the network used to encode the light fields.

• CUDA
• PyTorch
• Numpy
• PIL

To decode an image at light field view point (u, v), please run

• python demo_decode.py -u [u] -v [v] --scene [scene_name]
• u and v are integers within the range [0, 16], specifying the viewpoint coordinates in the original light field We provide the pretrained weights for scenes "lego" and "tarot" in the encoded_weights folder.
