  abstract = {This article proposes a technique to animate a Chinese style
              painting given its image. We first extract descriptions of the
              brush strokes that hypothetically produced it. The key to the
              extraction process is the use of a brush stroke library, which is
              obtained by digitizing single brush strokes drawn by an
              experienced artist. The steps in our extraction technique are
              first to segment the input image, then to find the best set of
              brush strokes that fit the regions, and, finally, to refine these
              strokes to account for local appearance. We model a single brush
              stroke using its skeleton and contour, and we characterize texture
              variation within each stroke by sampling perpendicularly along its
              skeleton. Once these brush descriptions have been obtained, the
              painting can be animated at the brush stroke level. In this
              article, we focus on Chinese paintings with relatively sparse
              strokes. The animation is produced using a graphical application
              we developed. We present several animations of real paintings
              using our technique.},
