Video processing system and method for automatic enhancement of digital video

A method for processing a video having a video frame sequence, comprising:

• computing global alignment affine transforms using the video frame sequence to reduce camera motion;
• computing optic flow vectors using the global alignment affine transforms and the video frame sequence;
• and
• performing deinterlacing on the video frame sequence using the optic flow vectors and a temporal median filter with flow outlier rejection to generate a denoised, deinterlaced video.

A method for processing a video containing a video frame sequence, comprising:

• performing global motion computation to using an affine transformation to generate global alignment affine transforms;
• performing warp stabilization on the video frame sequence using the global alignment affine transforms;
• wherein performing warp stabilization further comprises:
• discovering any blurry frames within the video frame sequence;
• discarding the blurry frames;
• synthesizing new frames using the global alignment affine transforms;
• and
• replacing the discarded blurry frames with the new frames.

A method for processing a video containing a video frame sequence, comprising:

• performing global motion computation to using an affine transformation to generate global alignment affine transforms;
• performing warp stabilization on the video frame sequence using the global alignment affine transforms, wherein the warped stabilization is a damped stabilization, and performing the warp stabilization further comprises:
• determining a curve corresponding to an actual motion of a camera that captured the video;
• applying a smoothing operation to the actual camera motion to yield an intended camera motion;
• and
• determining the difference between the intended camera motion and the actual camera motion to recover camera jitter.

A method for processing a video containing a video frame sequence, comprising:

• performing global motion computation to using an affine transformation to generate global alignment affine transforms;
• performing warp stabilization on the video frame sequence using the global alignment affine transforms, wherein the warned stabilization is a locked stabilization, and performing the warp stabilization further comprises:
• determining a video frame from the video frame sequence to use as a reference frame;
• and
• canceling out moving pixels in a video frame discovered by the global alignment affine transforms.
