Latest Patents

Among his notable inventions, two key patents stand out:

1. **Broadened-Specular Reflection and Linear Subspaces for Object Recognition**

This innovative method involves deriving a reflectance function that analytically approximates light reflected from an object model through the spherical harmonic components of light. This reflectance function takes into account the intensity of light incident at specific points, the intensity of light diffusely reflected, and the intensity of broadened-specular light reflected towards an observer. This technology enhances machine vision by optimizing the reflectance function, thus enabling more robust recognition of images under varying lighting conditions. Additionally, the function has implications in the realm of computer graphics.

2. **Cast Shadows and Linear Subspaces for Object Recognition**

This patent also revolves around the development of a reflectance function that excludes light originating from below a local horizon, effectively filtering out contributions from cast shadows. Similar to the previous invention, this reflectance function aids in machine vision, helping to derive optimal rendered images of object models. The result is a system that performs efficiently even under diverse lighting conditions and presents possible applications within computer graphics.
