Claim Text:
1. A method for smoothing an image representing one of foreground and background by performing data filling on the image, comprising: dividing the image into a plurality of blocks at a specified granularity; filling a block of the plurality of blocks containing a blank pixel and a non-blank pixel, by modifying a first value of the blank pixel of the block to a second value obtained on the basis of a third value of the non-blank pixel, to obtain a filled block; smoothing by obtaining a smoothed block in which values of pixels are smoothed by singular value decomposition on a matrix of pixels of a filled block, wherein values, in the matrix of pixels of the smoothed block in which values of pixels are smoothed, are calculated as a product of an obtained singular value, a left singular vector and a transpose of a right singular vector; and reconstructing, for each of the non-blank pixels in the smoothed block in which the values of the pixels are smoothed, by restoring values of the non-blank pixels to initial values of the non-blank pixels before filling to obtain a reconstructed block.
