  • Patent number: 9418307
    Abstract: 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.
