About this technology

Overview

Just as web search involves more than matching phrases, spectral search is more challenging than simply matching the shape of the spectrum. The background substrate and illumination changes can cause the same signature to appear very different across scenes. Here, the search service uses an adaptive matched-filter approach that compensates for the context and background characteristics of each scene.
