  • Liu, Lifeng; Sclaroff, Stan (Boston University Computer Science Department, 1997-11-24)
    A new deformable shape-based method for color region segmentation is described. The method includes two stages: over-segmentation using a traditional color region segmentation algorithm, followed by deformable model-based ...
  • Liu, Lifeng; Sclaroff, Stan (Boston University Computer Science Department, 1998-12-04)
    A method for deformable shape detection and recognition is described. Deformable shape templates are used to partition the image into a globally consistent interpretation, determined in part by the minimum description ...
  • Liu, Lifeng; Sclaroff, Stan (Boston University Computer Science Department, 2000-03-22)
    An improved method for deformable shape-based image indexing and retrieval is described. A pre-computed index tree is used to improve the speed of our previously reported on-line model fitting method; simple shape features ...
  • Liu, Lifeng; Sclaroff, Stan (Boston University Computer Science Department, 2000-12-04)
    An improved method for deformable shape-based image segmentation is described. Image regions are merged together and/or split apart, based on their agreement with an a priori distribution on the global deformation parameters ...
  • Liu, Lifeng; Sclaroff, Stan (Boston University Computer Science Department, 2001-06)
    Based on our previous work in deformable shape model-based object detection, a new method is proposed that uses index trees for organizing shape features to support content-based retrieval applications. In the proposed ...
