Abstract
The present disclosure provides systems and methods for detecting and interpolating still pixels. In certain embodiments, the systems and methods establish a still pixel level for each still pixel, and using that still pixel level, provide an interpolation procedure for determining the pixel value of a selected pixel at a frame a distance α from frame F(t−1). Disclosed embodiments are capable of providing motion compensated interpolation results for a wide variety of circumstances, including cases where the endpoints of the motion vector of a selected pixel to be interpolated vary between substantially still and not still, as well as cases where mixtures of temporal and motion compensation interpolations are necessary. Still pixel candidates may be refined in a process where pixels that may be properly handled by standard motion compensation interpolation techniques are eliminated. Further, still pixel candidates may be flagged as high or low likelihood to further enhance confidence in the detected still pixels.
