English: Visual representation of the kernel of the Kawase's Bloom Filter, or equivalently the images obtained by applying the filter on 1-pixel-sized luminous dot. From up to bottom: initial state (a luminous dot), the kernel of 1-path filter, that of 2-path filter, ..., that of 6-path filter. The figure on left is the raw image and on right is the luminosity-normalized image so that the pixels have value 255 at the maximum.
