In this work, we extend the Euclidean wavelets to the sphere. The resulting over-complete spherical wavelets are invariant to rotation of the parameterization of the original spherical image. We apply the over-complete spherical wavelet to cortical folding development and show significantly consistent results as well as improved sensitivity compared with the previous methods of using bi-orthogonal spherical wavelet. In particular, we were able to detect developmental asymmetry in the left and right hemispheres.
