Extract scaled number of consecutively matching striation marks (peaks and valleys) from two aligned signatures

Usage

extract_feature_cms_per_mm(striae, aligned, resolution)

Arguments

striae: data frame of striation marks based on two aligned signatures
aligned: two aligned signatures
resolution: micron per pixel resolution

Value

scaled number of consecutively matching striation marks (peaks and valleys)

Examples

if (FALSE) { # \dontrun{
# Set the data up to be read in, cleaned, etc.
