Latest Patents

One of her latest patents is titled "Pixel modification to reduce energy consumption of a display device." This invention proposes a method and device that reduces the total amount of light emitted in a perceptually indistinguishable manner, based on human visual sensitivity at the position of a pixel. The processing visibility remains provably below threshold, which is a significant advantage over other techniques. This is achieved by determining a minimum detectable modulation or a corresponding just-noticeable difference based on frequency intensity information for a pixel. The contrast sensitivity function may be modeled using Barten's model, and the frequency intensity information may be based on a hierarchical map built using discrete or continuous wavelet transforms.

Another significant patent is a "Method or an apparatus for estimating film grain parameters." This invention presents a method for efficiently processing film grain while encoding or decoding video. The method involves estimating film grain parameters for multiple image blocks, which include at least one scaling factor. This process is crucial for obtaining a film grain estimate in an image block and determining scaling factors adapted to the statistics based on the film grain blocks and filtered blocks.
