The original formulation comprised of aniline gentian violet, Lugol's iodine, absolute alcohol and Bismarck brown. Stains were introduced within the mid-19th century that are to blame for the foremost advances that have occurred in clinical biological science and diagnostic research throughout the past one hundred years years.. Stains contain liquid or organic preparations of dyes or teams of dyes that impart a range of colours to microorganisms so that identification of bacteria will be done easily. The conventional stain normalization usually achieves through a pixel-by-pixel color mapping model, which depends on one reference image, and it is hard to achieve accurately the style transformation between image datasets.
