Latest Patents

One of Yiwei Hu's latest patents is titled "Target-augmented material maps." This invention relates to rendering images using target-augmented material maps. In this process, a graphics imaging application is loaded with a scene and an input material map, along with a file for a target image. The application accesses a stored material generation prior, which is based on a pre-trained generative adversarial network (GAN). The input material appearance is encoded to produce a projected latent vector, which is then optimized to create a material map that enhances the scene with a realistic target material appearance.

Another notable patent is "Node graph optimization using differentiable proxies." This invention focuses on optimizing a material graph to replicate the material of a target image. The process involves receiving a target image and a material graph that needs optimization. It identifies a non-differentiable node within the material graph and selects a differentiable proxy from a library. The optimized input parameters for the non-differentiable node are generated using a trained neural network, ultimately producing an output material that accurately represents the target image.
