A database is selected from a plurality of databases included in the distributed database cluster. A shard map of the database is acquired, wherein the shard map includes a distribution of a plurality of shards on the plurality of nodes, and one or more nodes of the plurality of nodes each includes at least one shard of an old version of the database to be upgraded to a new version. A sustainable serviceability of the database corresponding to each of the one or more nodes is predicted according to the shard map based on the assumption that the at least one shard of each of the one or more nodes has been upgraded from the old version to the new version.

Embodiments of the present disclosure relate to a method for closing a plurality of webpages in a browser. According to the method, one or more records are acquired in response to receiving an instruction to close a first webpage. Each record comprises at least two URLs having a parent-child relationship. A URL chain of the first webpage is acquired based on the acquired one or more records in response to receiving an instruction to close a plurality of webpages related to the URL chain. The URL chain consists of a plurality of URLs having a multi-level parent-child relationship. The plurality of webpages related to the URL chain are closed.

A method and apparatus for smoothing an image representing foreground or background. The method comprises: dividing the image in a specified granularity; for a block divided containing a blank pixel and a non-blank pixel, modifying a value of the blank pixel to a value obtained from a value of the non-blank pixel to obtain a filled block; obtaining the block smoothed by performing singular value decomposition on a matrix of pixels of the filled block, wherein values in the matrix of pixels of the block smoothed is calculated as a product of the obtained singular value, a left singular vector, and a transpose of a right singular vector; and for each of the non-blank pixels in the block smoothed, restoring the values of the non-blank pixels to initial values before the filling step, so as to obtain a reconstructed block.

A method and a device for extracting a distorted straight line from an image. The method includes performing a line segment detection process on the image; for each line segment detected, finding adjacent line segments having a low non-collinear degree with a current line segment, so as to combine them together to obtain one or more line segment combinations; and extracting the distorted straight line according to the line segment combination.

An apparatus and a method for extracting a background luminance map of an image, and a de-shading apparatus and method. The apparatus includes: a luminance extracting unit, configured to extract luminance values everywhere in the image to obtain a luminance map; a separating unit, configured to separate background from foreground of the image based on the luminance map, to obtain an initial background luminance map; a top and bottom luminance obtaining unit, configured to extract top and bottom luminance of the initial background luminance map, and in the case of a part of the top and/or bottom luminance being missing, to supplement the missing part utilizing existing data of the top and/or bottom luminance to obtain complete top and bottom luminance; and an interpolation unit, configured to perform interpolation on the whole image based on the complete top and bottom luminance, to obtain the background luminance map of the image.
