Linear detection
Description
Function for developing linear detection of ring borders.
Usage
linearDetect(smoothed, origin = 0, darker = TRUE)
Arguments
smoothed |
a data frame with smoothed grays such as that
produced by graySmoothed .
|
origin |
numeric. an origin in smoothed gray to find the
ring borders.
|
darker |
logical. If TRUE the algorithm uses the
negative extremes on smoothed grays to detect the ring
borders. If FALSE the possitive extremes are used.
|
Value
vector with column numbers in gray matrix of the detected
ring borders (see grayDarker , and
graySmoothed ).

Examples
## (not run) Read one image section in package measuRing:
image1 <- system.file("P105_a.tif", package="measuRing")
## (not run) smoothed gray:
smoothed <- graySmoothed(image1)
## linear detection:
borders <- linearDetect(smoothed)
str(borders)
