Film grain analysis, synthesis, and removal

A non-transitory computer-readable storage medium having stored thereon computer executable instructions, which when executed by a computing device, cause the computing device to be operable for:

• analyzing, by a grain analysis system, a first video frame and outputting respective first film grain information for film grain that is included in the first video frame or analyzing a second video frame and outputting second film grain information;
• and
• at least one of:
• removing, by a grain removal system, the film grain from the first video frame using the first film grain information to generate a third video frame corresponding to the first video frame with film grain removed, wherein the grain analysis system is separate from the grain removal system;
• or
• synthesizing, by a grain synthesis system, film grain for the third video frame using the first film grain information or the second film grain information, wherein the grain analysis system is separate from the grain synthesis system.

A method comprising:

• analyzing, by a grain analysis system, a first video frame and outputting respective first film grain information for film grain that is included in the first video frame or analyzing a second video frame and outputting second film grain information;
• and
• at least one of:
• removing, by a grain removal system, the film grain from the first video frame using the first film grain information to generate a third video frame corresponding to the first video frame with film grain removed, wherein the grain analysis system is separate from the grain removal system;
• or
• synthesizing, by a grain synthesis system, film grain for the third video frame using the first film grain information or the second film grain information, wherein the grain analysis system is separate from the grain synthesis system.
