Latest Patents

One of Wang's latest patents is titled "Mutual information regularized Bayesian framework for multiple image restoration." This method involves receiving multiple images that have been corrupted by noise and initializing a reduced noise estimate. The process includes estimating the probability distributions of noise around each pixel and the signal, as well as calculating mutual information between the noise across the images. This innovative approach allows for the updating of each pixel within a search range to produce a restored image by minimizing the mutual information between the noise on the images.

Another significant patent is "Gradient-based image restoration and enhancement." This method employs an orientation-isotropy adaptive filter to enhance and restore images by applying it to the gradients of high-structured regions. The technique suppresses gradients in noise or texture regions, leading to a new gradient field that facilitates image reconstruction through least mean squares. The process involves inputting image data, calculating gradients, filtering for edge enhancement, and optimizing the assembled gradient field into a restored image.
