\title{Identify the local maximum of each column in 2-D CWT coefficients matrix}
\description{
Identify the local maximum of each column in 2-D CWT coefficients matrix by using a slide window.
The size of slide window linearly changes from the coarse scale (bigger window size) to detail scale.
The scale of CWT increases with the column index.
}
\usage{
getLocalMaximumCWT(wCoefs, minWinSize= 5, amp.Th = 0)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{wCoefs}{2-D CWT coefficients, each column corresponding to CWT coefficient at one scale. The column name is the scale.}
  \item{minWinSize}{The minimum slide window size used.}
  \item{amp.Th}{ The minimum peak amplitude. }
}

\value{
return a matrix with same dimension as CWT coefficient matrix, wCoefs. The local maxima are marked as 1, others are 0.
