Latest Patents

Feng Xiao holds a patent titled "System and method for estimating physical properties of objects and illuminants in a scene using modulated light emission." This invention focuses on color balancing algorithms for digital image processing, which require an accurate estimate of the ambient scene illuminant's spectral power distribution. The active imaging method and apparatus he developed emit modulated light with a known spectral power distribution into a scene. By detecting and demodulating backscattered light, the system separates the output representing active emitter light from that of the ambient illuminant light. This allows for the computation of the surface spectral reflectance function and subsequently the spectral power distribution of the ambient scene illuminant. The estimated spectral power distribution can then be utilized in standard color balancing algorithms for both digital and film images. Feng Xiao has 1 patent to his name.
