摘要： Briefly, in accordance with a preferred embodiment of the present principles, simulation of a block of film grain for addition to a block of an image occurs by first establishing at least one image parameter in accordance with at least one attribute of the block. Thereafter, a block of film grain is established in accordance with the image parameter. Deblocking filtering can be applied to the film grain block.

摘要： The simulation of film grain in an image makes use of parameters contained in a Supplemental Enhancement Information (SEI) message that accompanies the image upon transmission. The SEI message specifies film grain simulation parameters such as the film simulation model, the blending mode, and color space.

摘要： The simulation of film grain in a video image occurs by first creating a block (i.e., a matrix array) of transformed coefficients for a set of cut frequencies fHL, fVL, fHH and fVH associated with a desired grain pattern. (The cut frequencies fHL, fVL, fHH and fVH represent cut-off frequencies, in two dimensions, of a filter that characterizes the desired film grain pattern). The block of transformed coefficients undergoes an inverse transform to yield a bit-accurate film grain sample and the bit accurate sample undergoes scaling to enable blending with a video signal to simulate film grain in the signal.
