Latest Patents

Wanyuan Cai holds a patent for a "Hyperspectral image distributed restoration method and system based on graph signal processing and superpixel segmentation." This novel mixed-noise removal method is designed for hyperspectral images (HSI) of large sizes. The method begins by modeling the underlying structure of the HSI using a two-layer architecture graph. The upper layer, known as the skeleton graph, is constructed using a modified k-nearest-neighborhood algorithm. Its nodes correspond to superpixels formed by HSI segmentation, efficiently characterizing inter-correlations between superpixels while preserving boundary information and reducing computational complexity. The lower layer, referred to as the detailed graph, consists of local graphs that model similarities between pixels. The HSI restoration problem is then formulated as a series of optimization problems, each residing on a subgraph. A novel distributed algorithm is tailored for the restoration problem, utilizing information interaction between the nodes of the skeleton graph and subgraphs.
