摘　　要：Image-guided drawing can compensate for a lack of skill but often requires a significant number of repetitive strokes to create textures.Existing automatic stroke synthesis methods are usually limited to predefined styles or require indirect manipulation that may break the spontaneous flow of drawing.We present an assisted drawing system to autocomplete repetitive short strokes during a user's normal drawing process.Users draw over a reference image as usual;at the same time,our system silently analyzes the input strokes and the reference to infer strokes that follow the user's input style when certain repetition is detected.Users can accept,modify,or ignore the system's predictions and continue drawing,thus maintaining fluid control over drawing.Our key idea is to jointly analyze image regions and user input history to detect and predict repetition.The proposed system can effectively reduce the user's workload when drawing repetitive short strokes,helping users to create results with rich patterns.
