These programs, completed as a graduation project in 2019, restore illumination from singe image using neural network(ResNext) and render the scene using image-based lighting in OpenGL.

The neural network is based on [Hold-Geoffroy et al. CVPR 2017] (https://arxiv.org/abs/1611.06403), many different CNN framework is being evaluated to improve the performance.
The pinhole image dataset is sampled on a panorama dataset 360SP, which also provide part of the parameter needed for the network. The rest of the parameter is estimated using the methods provided in Hold-Geoffroy
HDR image for IBL is generated using Hošek-Wilkie sky model.
