Method Detail

contour

public void contour(FImage image,
                    Pixel start,
                    Pixel from,
                    Operation<Pixel> operation)

Description copied from class: ContourFollowingStrategy

Given some starting pixel in an image on a contour and the direction of a non starting image, return each pixel on a contour from the start pixel in the image. The first pixel returned must be the start pixel

Specified by:

contour in class ContourFollowingStrategy

Parameters:

image - the image

start - the first point on the contour

from - the pixel that was not a contour

operation - the thing to do for each contour pixel found

directedContour

public void directedContour(FImage image,
                            Pixel start,
                            Pixel from,
                            Operation<IndependentPair<Pixel,org.openimaj.image.contour.Direction>> operation)

Directed contour following.

Parameters:

image - the image

start - the starting point on the contour

from - the pixel that was not a contour

operation - the operation to perform
