Spectral Edge, the image fusion technology specialists, has secured $5.3 million in further funding from existing investors Parkwalk Advisors and IQ Capital. Based in Cambridge with deep academic roots, Spectral Edge combines cutting-edge imaging science with machine learning to improve pictures and videos on mass-market devices. This is done in real time with a pixel-level, embeddable technology that can be implemented in software or in silicon.

The technology behind the process can be used across a range of potential applications that rely on image quality for either function or aesthetics - from mobile to security, and from automotive to on-demand video or live broadcast.
