Reconstruction
This transformation is non-redundant, approximately shift-invariant and produces oriented filters in 2D and 3D. There is a m-file called 'example.m' which shows how one can use this package.For more information see the following paper:Hosseini, Vafadust : "Almost Perfect Reconstruction Filter...

Raw MRI data are generated analytically from k-space coordinates using the (continuous) Shepp and Logan head phantom function. K -space coordinates are typically entered as 2D matrices (frequency and phase encodes).This tool is ideal for testing reconstruction of non-linear k-space trajectory MRI...

Often three dimensional objects need to be reconstructed from planar images that are taken from slices in destructive testing. This sometimes requires the manual selecting of control points, but in this case geometries of the solid can be exploited to realign the images automaticaly. This is an...
