Abstract
A method of smoothing jagged edges in graphical data. The method detects one or more edge of a selected pixel in the graphical data, dependent upon intensities of the selected pixel and another pixel surrounding a respective site of one or more edges and predetermied gradients of at least the selected pixel and the respective site surrounding the pixel. An adapted convolution mask is applied to the selected pixel and a predetermined neighborhood of pixels containing the selected pixel. The coefficient values of the convolution mask are dependent upon one or more detected edges.
