NAME

dilate - morphological dilation of binary images

SYNOPSIS

E = dilate(Img, [SE, center])

PARAMETERS

Img

M x N Binary image to be dilated. (0 for background, 1 for object)

M x N Binary dilated image.

Arbitrary structuring element represented as a binary array. Defaults to:

            [0 1 0
             1 1 1
             0 1 0]

center

origin of structuring element. Shold be within image dimensions. Defaults to the center of the SE array.

DESCRIPTION

Function dilate performs morphological dilation of a binary image Img using SE as the structuring element.

EXAMPLE

Img = imread(SIPDIR+'images/tru.jpg');
Img = 1-im2bw(Img, 0.3);
Img = thin(Img);
xbasc()
imshow(Img ,2);

e = dilate(Img);
xbasc()
imshow(e ,2);

SE = eye(10,10);
e = dilate(Img, SE, [1,1]);
xbasc()
imshow(e ,2);

REMARKS

The algorithm is fully functional, but there exists many better ones. The present implementation will certainly change, but the interface shall remain unaltered.
