Uses the "crazy climber algorithm" to detect ridges in the modulus of a continuous wavelet or a Gabor transform.
1 2 3 |
tfrep |
modulus of the (wavelet or Gabor) transform. |
tfspec |
numeric vector which gives, for each value of the scale or frequency the expected size of the noise contribution. |
bstep |
stepsize for random walk of the climbers. |
iteration |
number of iterations. |
rate |
initial value of the temperature. |
seed |
initial value of the random number generator. |
nbclimb |
number of crazy climbers. |
flag.int |
if set to TRUE, the weighted occupation measure is computed. |
chain |
if set to TRUE, chaining of the ridges is done. |
flag.temp |
if set to TRUE: constant temperature. |
Returns a 2D array called beemap containing the (weighted or unweighted) occupation measure (integrated with respect to time)
