scrcrec: Simple Reconstruction from Crazy Climbers Ridges

In Rwave: Time-Frequency Analysis of 1-D Signals

Simple Reconstruction from Crazy Climbers Ridges

Description

Reconstructs signal from ridges obtained by crc, using the restriction of the transform to the ridge.

Usage

scrcrec(siginput, tfinput, beemap, bstep=5, ptile=0.01, plot=2)

Arguments

siginput	input signal.
tfinput	time-frequency representation (output of cwt or cgt.
beemap	output of crazy climber algorithm
bstep	used for the chaining (see cfamily).
ptile	threshold on the measure beemap (see cfamily).
plot	1: displays signal,components, and reconstruction one after another. 2: displays signal, components and reconstruction. Else, no plot.

Value

Returns a list containing the reconstructed signal and the chained ridges.

rec	reconstructed signal
ordered	image of the ridges (with different colors)
comp	2D array containing the signals reconstructed from ridges
