Introduction

Clay Douglas Spence is an accomplished inventor based in Princeton Junction, NJ (US). He holds a total of 13 patents that showcase his expertise in signal processing and filtering techniques. His innovative contributions have significantly advanced the field of technology.

Latest Patents

One of his latest patents is the "Geometric source separation signal processing technique." This invention involves a computer system that processes mixtures of signals, such as speech and noise, derived from multiple simultaneous microphone recordings. The system separates these signals into their underlying sources by optimizing a filter structure that minimizes cross powers of multiple output channels while enforcing geometric constraints on the filter response. These constraints ensure desired responses for given locations of the underlying sources, based on the assumption that the sources are localized in space.

Another notable patent is the "Method and system for filtering, registering, and matching 2.5D normal maps." This invention presents an iterative approach to vector median filtering, allowing for fast convergence for complex computations. The output is approximate to the mean, particularly for small data sets. Additionally, the method provides a system for registering and matching 2.5D normal maps by optimally aligning their normals through 2-D warping in the image plane, combined with a 3-D rotation of the normals. The average dot-product serves as a matching metric for automatic target recognition (ATR).
