Optic disk feature extraction via modified deformable model technique for glaucoma analysis

  title={Optic disk feature extraction via modified deformable model technique for glaucoma analysis},
  author={Juan Xu and Opas Chutatape and Eric Sung and Ce Zheng and Paul Chew Tec Kuan},
  journal={Pattern Recognition},
A deformable-model based approach is presented in this paper for robust detection of optic disk and cup boundaries. Earlier work on disk boundary detection up to now could not effectively solve the problem of vessel occlusion. The method proposed here improves and extends the original snake, which is essentially a deforming-only technique, in two aspects: knowledge-based clustering and smoothing update. The contour deforms to the location with minimum energy, and then self-clusters into two… CONTINUE READING
