Latest Patents

One of her latest patents is titled "Gamut clipping with preprocessing." This invention provides a method for gamut clipping with preprocessing enabled as software instructions stored in a computer-readable medium and executable by a processor. The instructions define a color in a color space characterized by at least three attributes. If the color lies outside a gamut boundary in the first color space, a distance is measured from the color to the gamut boundary. In response to the measured distance, a weight is calculated for an attribute of the color. It is then determined if the attribute of the color is to be shifted. If so, an attribute shift amount is derived and modified by applying the weighting. The attribute of the first color is shifted by the weighted attribute shift amount, creating a post-processed color, which is then clipped.

Another notable patent involves "Methods, systems and apparatus for jointly calibrating multiple displays in a display ensemble." This invention relates to systems, methods, and apparatus for the calibration of multiple display apparatus in a display ensemble, showcasing her expertise in improving display technologies.
