1. A method performed by a processing system, the method comprising:
- determining a correspondence between a first pixel value in a first frame of a digital video and a second pixel value in a second frame of the digital video;
processing the first pixel value and the second pixel value to remove noise and generate a third pixel value; and
re-mapping the first pixel value in the first frame with the third pixel value.

13. A system comprising:
-
a processor; and
a memory system for storing a digital video and a video enhancement module;
wherein the processor is configured to execute the video enhancement module to;
determine a correspondence between a first plurality of pixel values in a first frame of a digital video and a second plurality of pixel values in a second frame of the digital video;
process the first plurality of pixel values and the second plurality of pixel values to remove noise and generate a third plurality of pixel values; and
re-map the first plurality of pixel values in the first frame with the third plurality of pixel values. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A system comprising:
-
means for determining a first correspondence between a first pixel value in a first frame of a digital video and a second pixel value in a second frame of the digital video;
means for determining a second correspondence between the first pixel value in the first frame and a third pixel value in a third frame of the digital video;
means for processing the first pixel value, the second pixel value, and the third pixel value to remove noise and generate a fourth pixel value; and
means for re-mapping the first pixel value in the first frame with the fourth pixel value. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
