Gaussian smoothing is also used as a pre-processing stage in computer vision algorithms in order to enhance image structures at different scales-see scale space representation and scale space implementation. The visual effect of this blurring technique is a smooth blur resembling that of viewing the image through a translucent screen, distinctly different from the bokeh effect produced by an out-of-focus lens or the shadow of an object under usual illumination.
