Directive Contrast Based Multimodal Medical Image Fusion in NSCT Domain (2013, background): “NSCT, based on the theory of CT, is a kind of multi-scale and multi-direction computation framework of the discrete images [29].”
The Discrete Shearlet Transform: A New Directional Transform and Compactly Supported Shearlet Frames (2010, methodology): “We compared the performance of the extended DST to other transforms such as the Nonsubsampled Contourlet Transform (NSCT)[17] and Translation Invariant Wavelet Transform”

Multifocus Image Fusion and Restoration With Sparse Representation (2010, methodology): “For the CVT- and NSCT-based method, the K in (19) is set to 4 for the finest scale and set to 3 for the remaining scales according to successful cases [27].”
A survey of classical methods and new trends in pansharpening of multispectral images (2011, methodology): “Similarly to wavelets, contourlets also have different implementations of the subsampled and non-subsampled [43] transforms.”
Performance comparison of different multi-resolution transforms for image fusion (2011, methodology): “The nonsubsampled version of the CT, the NSCT, is implemented via the ''à trous " algorithm [32].”
