FIELD: information technologies. ^ SUBSTANCE: length of transition at jumps in brightness is reduced; filtration with adaptive smoothing filter is done; repeatedly length of transition is reduced at jumps in brightness; local contrast is increased at the edges of jumps in brightness; global contrast is increased. ^ EFFECT: development of new method that increases efficiency of raster removal from screened scanned images, at the same time global and local contrast should be preserved at sufficient sharpness of image. ^ 4 cl, 10 dwg |
