Boundary-artifact-free phase retrieval with the transport of intensity equation : fast solution with use of discrete cosine transform
The transport of intensity equation (TIE) is a two-dimensional second order elliptic partial differential equation that must be solved under appropriate boundary conditions. However, the boundary conditions are difficult to obtain in practice. The fast Fourier transform (FFT) based TIE solutions are...
