Shading Correcting Network
Measure issue with reconstructin faces using Shading, Albedo, Normal and Spherical Harmonics is little variations in normal and spherical harmonics causing different illumination.
Estimating Normal and Spherical Harmonics with slight error causes different illumination and expected. In order to overcome this problem, we would like to using correcting networks
1_Shading_Correcting works on priciple built on top of tradition shading generation using normal and spherical harmonics We generate Shading and then rectify it using latent ligthing generated from Normal, Albedo and Image features.
2_Latent_Shading_Gen works on principle to avoid generation of Spherical Harmonics and instead generate shading directly using Normal, Albedo and Image features. And then use this latent lighting along with Normal to generate shading
