Latest Patents

Chao Liu's latest patents focus on enhancing material classification methods. The first patent involves a comprehensive system for material classification of an object. This system accesses various parameters for classification, including selections for a subset of angles, spectral bands, texture features, and image-level features. By illuminating the object and computing a feature vector based on these parameters, the system effectively classifies the material from which the object is fabricated.

The second patent introduces a method for material classification using multiplexed illumination. This technique employs broadband spectral light from multiple incident angles, combined with multi-spectral narrow band spectral measurements of light reflected from the object. The selection of spectral bands for illumination or narrow-band capture is based on an analysis of a database of labeled training material samples. This method aims to select a smaller subset of spectral bands that retain significant aptitude for distinguishing between different classifications of materials.
