A New Contourlet Transform with Sharp Frequency Localization
The contourlet transform was proposed as a directional multiresolution image representation that can efficiently capture and represent singularities along smooth object boundaries...

Contourlets: a directional multiresolution image representation
We propose a new scheme, named contourlet, that provides a flexible multiresolution, local and directional image expansion. The contourlet transform is realized efficiently via a ...

Extending the Depth of Field in Microscopy Through Curvelet-Based Frequency-Adaptive Image Fusion
Limited depth of eld is an important problem in microscopy imaging. 3D objects are often thicker than the depth of eld of the microscope, which means that it is optically impossib...
