DanielsonLineDetector

Line detector

SYNOPSIS

#include "dip_orientation.h"

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

DATA TYPES

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.
