Radially averaged power spectrum of 2D real-valued matrix (Scripts) Publisher's description
from Evan Ruzanski
The radially averaged power spectrum (RAPS) is the direction-independent mean spectrum, i.e.
The radially averaged power spectrum (RAPS) is the direction-independent mean spectrum, i.e. the average of all possible directional power spectra. The radially averaged power spectrum provides a convenient means to view and compare information contained in 2-D spectra in 1-D. This function computes and plots the RAPS of an input matrix (does not consider corner values outside averaging radius). The image can be rectangular but must be 2-D (e.g., multi-color channel data is not supported). The spatial resolution of the data is also specified.
