gkernel {Rwave} | R Documentation |
Kernel for Reconstruction from Gabor Ridges
Description
Computes the cost from the sample of points on the estimated ridge and the matrix used in the reconstruction of the original signal.
Usage
gkernel(node, phinode, freqstep, scale, x.inc=1, x.min=node[1],
x.max=node[length(node)], plot=FALSE)
Arguments
node |
values of the variable b for the nodes of the ridge. |
phinode |
values of the scale variable a for the nodes of the ridge. |
freqstep |
sampling rate for the frequency axis. |
scale |
size of the window. |
x.inc |
step unit for the computation of the kernel. |
x.min |
minimal value of x for the computation of |
x.max |
maximal value of x for the computation of |
plot |
if set to TRUE, displays the modulus of the matrix of |
Value
matrix of the Q_2
kernel
