Abstract:
We present a method for generating a pencil drawing from a digital image using the feature geometric attributes obtained by analysis of image moment and texture of each region. Thus, the drawing results represent not only the local region information but also the feature characteristics. It is inspired and devised to correspond to a real pencil drawing process: A painter often divides a scene into regions, observes the distinctive features, and applies the pencil strokes accordingly. We have implemented the method and compared the results with Adobe Photoshop 5.0.
