What is 3D Discrete Curvelet Transform Overview about?

This document presents a 3D discrete curvelet transform that extends the 2D discrete curvelet transform described in a previous work. The 3D transform preserves important properties of the 2D transform, such as parabolic scaling and tightness. It also provides a sparse representation of singularities along surfaces in 3D data, analogous to how the 2D transform represents singularities along curves. The paper describes three implementations of the 3D transform: an in-core version, an out-of-core version for
