Abstract
In some embodiments, a method of processing a video sequence may include receiving an input video sequence having an input video sequence resolution, aligning images from the input video sequence, reducing noise in the aligned images, and producing an output video sequence from the reduced noise images, wherein the output video sequence has the same resolution as the input video sequence resolution. Other embodiments are disclosed and claimed.
Claims21
A method of processing a video sequence, comprising:
- receiving an input video sequence having an input video sequence resolution;
- aligning images from the input video sequence;
- reducing noise in the aligned images;
- and
- producing an output video sequence from the reduced noise images, wherein the output video sequence has a same resolution as the input video sequence resolution.
A video processing apparatus, comprising:
- a first module to receive an input video sequence having an input video sequence resolution;
- a second module coupled to the first module to align images from the input video sequence;
- a third module coupled to the second module to reduce noise in the input video sequence based on the aligned images;
- and
- a fourth module coupled to the third module to produce an output video sequence based on the reduced noise input video sequence, wherein the output video sequence has no greater resolution than the input video sequence resolution.
A processor-based electronic system, comprising:
- a processor;
- a memory coupled to the processor, the memory having instructions that, when executed by the processor,
- receive an input video sequence having an input video sequence resolution;
- align images from the input video sequence;
- reduce noise in the input video sequence based on the aligned images;
- and
- produce an output video sequence based on the reduced noise input video sequence, wherein the output video sequence has no greater resolution than the input video sequence resolution.
