DanielsonLineDetector

Line detector

SYNOPSIS

#include "dip_orientation.h"

dip_Error dip_DanielsonLineDetector ( in, line, energy, angle, boundary, sigma, truncation, flavour )

DATATYPES

binary, integer, float

FUNCTION

The Danielson line dectector uses second derivatives to detect lines in 2D images and to estimate their orientation. See the literature reference for an in-depth information on this detector.
