TLDR
In this paper, a method and apparatus for video sample interpolation with edge sharpening was proposed, whereby edge sharpness can be essentially preserved and/or enhanced in the interpolated image.Abstract:
A method and apparatus for video sample interpolation with edge sharpening, whereby edge sharpness can be essentially preserved and/or enhanced in the interpolated image. Image interpolation for an original two dimensional image is conducted along the horizontal and vertical directions separately using a 1D digital filter. In interpolating a new sample in the image, the digital filter is first used to obtain a temporary interpolation value for the new sample. Then, an appropriate amount of edge enhancement is calculated for the new sample location. The enhancement value is combined with the temporary interpolation value to result in a final interpolation value for the new sample.read more
