De-interlacing and frame rate upconversion for high definition video

A system to de-interlace an interlaced digital video comprising:

• a processor;
• a de-interlacing tool communicatively coupled to the processor, the deinterlacing tool including:
• a frame estimation module configured to estimate a first progressive scan video frame based at least in part on an interlaced video frame from an interlaced video;
• and
• a filter module coupled to the frame estimation module and configured to generate a second progressive scan video frame based at least in part on application of a nonlocal means filter to the estimated first progressive scan video frame.

A method to up-convert a video, the method comprising:

• inserting, by a computing device, an interpolated video frame between a first video frame and a second video frame of the video;
• determining, for each pixel in the interpolated video frame, whether the pixel is a background pixel based at least in part on pixels in the first video frame and pixels in the second video frame;
• setting, in response to determination that the pixel in the interpolated video frame is a background pixel, a value of the pixel in the interpolated video frame based at least in part on a value of a corresponding pixel in the first video frame and a value of a corresponding pixel in the second video frame;
• and
• setting, in response to determination that the pixel in the interpolated video frame is not a background pixel, the value of the pixel in the interpolated video frame based at least in part on application of a nonlocal means filter to the first video frame and the second video frame.

A machine readable non-transitory medium having stored therein instructions that, when executed by one or more processors, operatively enable a frame rate up-conversion (FRUC) tool to:

• insert an interpolated video frame between a first video frame and a second video frame of the video;
• determine, for each pixel in the interpolated video frame, whether the pixel is a background pixel based at least in part on pixels in the first video frame and pixels in the second video frame;
• set, in response to determination that the pixel in the interpolated video frame is a background pixel, a value of the pixel in the interpolated video frame based at least in part on a value of a corresponding pixel in the first video frame and a value of a corresponding pixel in the second video frame;
• and
• set, in response to determination that the pixel in the interpolated video frame is not a background pixel, the value of the pixel in the interpolated video frame based at least in part on application of a nonlocal means filter to the first video frame and the second video frame.

A system to upconvert the frame rate of a digital video comprising:

• a processor;
• and
• a frame rate up-conversion (FRUC) tool communicatively coupled to the processor, the FRUC tool configured to:
• insert an interpolated video frame between a first video frame and a second video frame of the video;
• the FRUC tool including a background determination module configured to determine, for each pixel in the interpolated video frame, whether the pixel is a background pixel based at least in part on pixels in the first video frame and pixels in the second video frame;
• the FRUC tool further including a filter module coupled to the determination module and configured to set, in response to determination that the pixel in the interpolated video frame is a background pixel, a value of the pixel in the interpolated video frame based at least in part on a value of a corresponding pixel in the first video frame and a value of a corresponding pixel in the second video frame;
• and
• the filter module is further configured to set, in response to determination that the pixel in the interpolated video frame is not a background pixel, the value of the pixel in the interpolated video frame based at least in part on application of a nonlocal means filter to the first video frame and the second video frame.
