Wavelet-based segmentation on the sphere

作者：

Highlights：

• Proposed a segmentation framework for images on the sphere, for the first time.

• It is compatible with any type of spherical wavelets.

• It is efficient and flexible for any type of spherical images.

• Devised a new hybrid directional-curvelet wavelet construction on the sphere.

• Numerical results with a series of applications are presented.
