Image and Video-based Non-Photorealistic Rendering / brush_stroke 3/14/2003

Each Brush stroke is an object with the following properties: Anchor point in image coordinates, angle of orientation in degrees, width in pixels, lengths in both directions from the anchor point in pixels, Color (R, G, B) for the current and past several frames, and opacity. In addition the brush stroke knows if it is ``new'' and/or if it is ``Strong.''
