Latest Patents
One of his latest patents is a method for embedding and extracting digital data in images and video. This method focuses on digital watermarking and allows for the hiding of significant amounts of data within images and video using a discrete wavelet transform. The technique can embed gray scale images that can be as large as 25% of the host image data. It employs a simple control parameter that can be adjusted for either hiding or watermarking purposes, ensuring robustness against operations like JPEG compression. Additionally, the method utilizes noise-resilient channel codes based on multidimensional lattices, enabling the embedding of signature data such as gray-scale or color images.
Another notable patent is a local relaxation method for estimating optical flow using a Poisson equation. This method enhances the convergence speed compared to conventional technologies and allows for accurate motion estimation in every pixel. It also provides compression gains in video coding by utilizing a portion of a motion vector.
