Abstract
A method includes receiving, at a processor, at least one frame of input image data, producing motion vector fields between the frames of input image data, and applying temporal stability to the at least one frame of the input image data to produce noise reduced image data, wherein applying temporal stability comprises separating pixel data into frequency bands.

A method, comprising:
- receiving, at a processor, at least one frame of input image data;
- producing motion vector fields between the frames of input image data;
- and
- applying temporal stability to the at least one frame of the input image data to produce noise reduced image data, wherein applying temporal stability comprises separating pixel data into frequency bands.

A method, comprising:
- receiving, at a processor, at least one frame of input image data;
- producing motion vector fields between the frames of input image data;
- applying temporal stability to the at least one frame of the input image data to produce noise reduced image data, wherein applying temporal stability comprises filtering a frame of input image data based upon motion errors in high and low frequency data, and separating pixel data into frequency bands based upon motion errors in the high and the low frequency data and error measurement ratios.
