  abstract = {This paper proposes a novel colorization technique that propagates
              color over regions exhibiting pattern-continuity as well as
              intensity-continuity. The proposed method works effectively on
              colorizing black-and-white manga which contains intensive amount
              of strokes, hatching, halftoning and screening. Such fine details
              and discontinuities in intensity introduce many difficulties to
              intensity-based colorization methods. Once the user scribbles on
              the drawing, a local, statistical based pattern feature obtained
              with Gabor wavelet filters is applied to measure the
              pattern-continuity. The boundary is then propagated by the level
              set method that monitors the pattern-continuity. Regions with open
              boundaries or multiple disjointed regions with similar patterns
              can be sensibly segmented by a single scribble. With the segmented
              regions, various colorization techniques can be applied to replace
              colors, colorize with stroke preservation, or even convert pattern
              to shading. Several results are shown to demonstrate the
              effectiveness and convenience of the proposed method.},
