Latest Patents

One of Chen's latest patents is titled "Differentiable object insertion using hybrid lighting volumes for synthetic data generation." This patent describes systems and methods that generate a hybrid lighting model for rendering objects within an image. The hybrid lighting model incorporates lighting effects from both a primary source, such as the sun, and a secondary source, which includes spatially-varying effects of objects within the image. This model allows for the rendering of virtual objects that seamlessly integrate into the input image, utilizing the hybrid lighting model to apply appropriate lighting effects.

Another notable patent is "Hybrid differentiable rendering for light transport simulation systems and applications." This invention involves receiving information for a 3D model, including geometry, lighting, and material information. A machine learning model is trained to disentangle this information from input data, enabling the projection of the 3D model's geometry onto an image plane. This process generates a mapping between pixels and portions of the 3D model, which can be used for various applications, including image editing and synthetic data generation.
