Abstract
An improved airbrush modeling routine is disclosed that can be implemented in a conventional electronic image reproduction system. The improved airbrush modeling routine incorporates an interpolation function with velocity smoothing to provide improved sampling of brush location during airbrushing operations by calculating the average velocity between sample intervals and determining average acceleration. In addition, randomness is introduced in the improved airbrush modeling routine to provide for a "textured" appearance in a retouched area of an original image.
