We present a method image-based non-photorealistic method which converts real picture to vector formatted painterly image. Our method extracts smoothly aligned 2D vectors that describe the smallest variation of colors within a bitmap image, and thus effectively preserves spatial coherence. As an application of this flow field we present a line segment-based image stylization technique to rerender the image in a vector formatted painterly style. Using our method, general user can easily create the painterly-rendered vector image using their own real pictures and it can also be used in various areas, such as smart phone user interface, web user interface and etc.
