Latest Patents

One of Rhemann's latest patents focuses on enhanced photo relighting based on machine learning models. This invention provides apparatus and methods related to applying lighting models to images of objects. The method includes applying a geometry model to an input image to determine a surface orientation map, which indicates the distribution of lighting on an object based on its surface geometry. Additionally, it involves applying an environmental light estimation model to ascertain the direction of synthetic lighting to be applied to the input image. The process further includes using a light energy model to determine a quotient image that indicates the amount of light energy to be applied to each pixel of the input image. This innovative approach enhances portions of the input image based on the quotient image, utilizing one or more trained neural networks.

Another notable patent by Rhemann is related to active stereo depth prediction based on coarse matching. This invention allows an electronic device to estimate a depth map of an environment by matching reduced-resolution stereo depth images captured by depth cameras. The device downsamples these depth images and matches sections of the reduced-resolution images to generate a coarse depth map. It then upsamples and refines this coarse depth map to produce a high-resolution depth map, supporting location-based functionality.
