Abstract
An apparatus and method for post processing image data which previously was encoded using a discrete cosine transform in order to remove resulting blocking effects. Possible blocking points are examined to determine whether blocking points exist. If blocking points are determined, an adjustment value for each blocking point is computed and proportionately utilized to adjust the adjacent and neighboring pixels.
