PyTorch implementation of "Spatial-Angular Interaction for Light Field Image Super-Resolution", ECCV 2020. [PDF] [Presentation]

Requirement

• PyTorch 1.3.0, torchvision 0.4.1. The code is tested with python=3.7, cuda=9.0.
• Matlab (For training/test data generation and performance evaluation)

Train

Please switch to LF-InterNet_train for details.

Test

• Download the test sets and unzip them to ./data. Here, we provide a demo test set (data_demo.zip) which only includes one test scene, and we also provide the full test set on Baidu Drive (Key: NUDT) which is used in our paper.
• Download our pretrained models (log.zip) and unzip them to ./log.
• Run GenerateDataForTest.m to generate test data.
• Run test.py to perform a demo inference. Note that, the selected pretrained model should match the generated input data and the preset network architecture. Initial results (.mat files) will be saved to ./results.
• Run evaluation.m to calculate PSNR and SSIM scores and transform initial results (.mat files) into .png images.
