BIT-ACCURATE FILM GRAIN SIMULATION METHOD BASED ON PRE-COMPUTED TRANSFORMED COEFFICIENTS |
摘要 |
<p>Bit-accurate creation of a film grain pattern 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.</p> |
