Computer Generation of Low Light-Level Images

As result of exposure in low light-level are images with only a small number of photons. Only the pixels in which arrive the photopulse have an intensity value different from zero. This paper presents an easy and fast procedure for simulating low light-level images by taking a standard well illuminated image as a reference. The images so obtained are composed by a few illuminated pixels on a dark background. When the number of illuminated pixels is less than 0.01% of the total pixels number it is difficult to identify the original object.
