Estimate the length of the ridge
Description
Estimate the length of the ridge line, which is composed of local maxima at
adjacent CWT scales. The ridge line is cut off at the end point, whose
amplitude divided by the maximum ridge amplitude is larger than the cutoff
amplitude ratio threshold (0.5 by default).
Usage
getRidgeLength(ridgeList, Th = 0.5)
Arguments
ridgeList
a list of identified ridges
Th
the cutoff amplitude ratio (the amplitude divided by the maximum
amplitude of the ridge) threshold of the ridge line end.
Value
a vector of estimated ridge length

Examples
stopifnot(getRidgeLength(list(c(5,4,3,2,1), c(5,3,1))) == c(3,2))
