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. The video processing device also includes an output to provide a second pixel value for the select pixel, the second pixel value based on the first pixel value, the vertical transient improvement value, the horizontal transient improvement value, the first diagonal transient improvement value, and the second diagonal transient improvement value.
