Latest Patents

One of his latest patents is a method of improving a color filter. This method involves a numerical generation of sinusoidal spectra, followed by two selection steps based on colorimetric similitude and the capacity of dummy filters to restore hues naturally. The process includes simulating observations of hues through each dummy filter using a color appearance model, ultimately leading to the determination of an improved filter that closely resembles the initial filter while providing a natural rendition of hues. Another significant patent focuses on the quantitative evaluation of a color filter. This evaluation utilizes a numerical color appearance model to calculate perceptive attributes for hue samples. The results allow for a quantitative ranking of several color filters, reflecting the evaluations that would be made by real observers.
