BIT-ACCURATE FILM GRAIN SIMULATION METHOD BASED ON PRE-COMPUTED TRANSFORMED COEFFICIENTS

Creation of a Bit-accurate film grain pattern for blending in an image block occurs by first establishing a set of bit-accurate transformed coefficients. The set of bit-accurate transformed coefficients undergo frequency filtering and a subsequent bit-accurate inverse transformation to yield the fil...

Summary:Creation of a Bit-accurate film grain pattern for blending in an image block occurs by first establishing a set of bit-accurate transformed coefficients. The set of bit-accurate transformed coefficients undergo frequency filtering and a subsequent bit-accurate inverse transformation to yield the film grain pattern. The film grain pattern can then undergo blending with an image block to restore the look of film to the image.
