Abstract: A method and system for detecting and processing a series of video frames includes receiving the series of video frames, determining whether the video frames are associated with a recognized non-video source, and depending on the determination, processing the video frames using a variety of techniques. A system may detect whether each video frame is a repeat frame or a new original frame, keep the new original frames, discard the repeat frames, and then adjust one or more timestamps associated with the new original frames so as to conform to an intermediate frame rate. The frame indexes and timestamps associated with the new original frames are stored in a FIFO or buffer. The system can interpolate video frames using the stored timestamps, and output a series of video frames. The output video stream is delivered at any frame rate and can include original video frames and interpolated video frames.

Abstract: To denoise video data, a temporal IIR filter is applied to video data. The temporally filtered frame is used as a guide to spatially filter the video data without introducing temporal artifacts. The spatially filtered frame can then be temporally filtered again using a temporal IIR filter. The results of the second temporal filtering can then be used as a guide to eliminate noise that the spatial filter did not eliminate.

Abstract: To determine if a pixel exhibits artifacts, statistics are generated for the pixel and its neighbors. These statistics are compared with thresholds. If the comparison of the statistics and the thresholds suggests that the pixel exhibits a pixel artifact, then recourse can be taken, either to adjust the pixel value in some way, or to reject the angle of interpolation used in computing the value for the target pixel.
