Function SCATTERGRAM
Package
display
Short description
Displays temporal evolution of scattering coefficients
Usage
img = SCATTERGRAM(X{m+1}, [j_1 j_2 ... j_(m-1)]);
img = SCATTERGRAM(X{m1+1}, [j_1 j_2 ... j_(m1-1)], ...
X{m2+1}, [j_1 j_2 ... j_(m2-1)]);
Input
X (struct): Scattering layer. Output S or U from SCAT.
Output
img (cell): Cell array of the images output given by the coefficients and
prefixes.
Description
Given a scattering layer of order m and a prefix of length (m-1), the
function constructs a image by varying the mth scale and time, creating
a time-frequency display. The scattering layer can be either a scattering
output S or a wavelet modulus output U.
To construct multiple displays, multiple pairs of scattering layer and
prefix can be given as input. The images generated are output as a cell
array of tables in img.
This function calls SCATTERGRAM_LAYER iteratively, in order to get the
scattering coefficients in a two-dimensional array, indexed by scale
and time.
