  • Adaptive edge enhancement using directional components from non-linear filtering
    Patent number: 8284314
    Abstract: A video processing device includes an input to receive pixel values for a set of pixels comprising a pixel window substantially centered around a select pixel that initially has a first pixel value. The video processing device further includes a first filter unit to determine a horizontal transient improvement value based on non-linear filtering of the pixel values in a horizontal direction, a second filter unit to determine a vertical transient improvement value based on non-linear filtering of the pixel values in a vertical direction, a third filter unit to determine a first diagonal transient improvement value based on non-linear filtering of the pixel values in a first diagonal direction, and a fourth filter unit to determine a second diagonal transient improvement value based on non-linear filtering of the pixel values in a second diagonal direction that is perpendicular to the first diagonal direction.
