The image foreground-background segmentation method uses the linear combination of graph Fourier basis functions to better represent the smooth background region. In addition, the graph Laplacian regularization is used to characterize the connectivity of foreground text and graphics while keeping sharp foreground text and graphics contours.

Abstract
Provide is a novel mixed-noise removal method for HSI with large size. First, the underlying structure of the HSI is modeled by a two-layer architecture graph. The upper layer, called a skeleton graph, is a rough graph constructed by using the modified k-nearest-neighborhood algorithm and its nodes correspond to a series of superpixels formed by HSI segmentation, which can efficiently characterize the inter-correlations between superpixels, while preserving the boundary information and reducing the computational complexity. The lower layer, called detailed graph, consists of a series of local graphs which are constructed to model the similarities between pixels. Second, based on the two-layer graph architecture, the HSI restoration problem is formulated as a series of optimization problems each of which resides on a subgraph. Third, a novel distributed algorithm is tailored for the restoration problem, by using the information interaction between the nodes of skeleton graph and subgraphs.

Abstract
Disclosed is an integrated preparation method for a lithium battery separator and a battery. The lithium battery separator comprises a three-layer structure, and the specific materials of the three-layer structure are shown as follows: a first layer base film: a lithium battery porous separator base film; a second layer insulating thermally stable layer: a ceramic powder or a thermally stable material, and a polymer binder; and a third layer active material layer: a positive electrode/negative electrode active material, a polymer material, and a conductive agent. In comparison to a battery assembled by using a commercially available separator, the separator and electrode integration mode of the present invention results in a high area specific capacity. Since an electrode active coating separator enhances the infiltration effect of an electrolyte on an electrode, the interface stability and compatibility between the electrode and the separator may be improved, and compared to independent inert ceramic coating separators, the electrode active coating separator has higher ionic conductivity. The integration of an electrode active coating and a ceramic separator into a whole also improves the mechanical performance and thermal stability of the separator, thus improving the safety performance of the battery.
