Title: Margalith Harrar: Innovator in Color Filter Technology
Introduction
Margalith Harrar is a prominent inventor based in Charenton le Pont, France. She has made significant contributions to the field of color filter technology, holding 2 patents that showcase her innovative approach to improving color perception.
Latest Patents
Harrar's latest patents include a method of improving a color filter and a quantitative evaluation of a color filter. The method of improving a color filter involves a numerical generation of sinusoidal spectra, where two selection steps are executed. The first selection is based on colorimetric similitude with respect to the initial filter, while the second selection assesses the capacity of dummy filters to restore hues naturally. This process utilizes a color appearance model to simulate human visual perception, ultimately leading to an improved filter that closely resembles the initial filter while providing a natural rendition of hues. The quantitative evaluation patent focuses on calculating perceptive attributes for hue samples by simulating observations through the filter and without it. This method allows for a quantitative ranking of color filters, aligning with evaluations made by real observers.
