Color perception of diffusion tensor images using hierarchical manifold learning

作者：

Highlights：

• A new method is proposed for color perception of DTI using hierarchical manifold learning.

• The novel method has better regional structures, which enhance image feature information and improve the visual effect.

• Our method reduces the computational complexity of the classical method [9] from O(N3) to O(N2).

• A new metric approximately estimates the geodesic distance between the seeds to avoid both great error and double counting.

• The proposed method focuses on the color perception of medical images application.
