NAME

edilate - euclidean morphological dilation of binary images

SYNOPSIS

Dil = edilate(Img, [radius, form])

PARAMETERS

Img

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

radius

- of circular euclidean structuring element to be used. Defaults to 5.

form

determines the size of Dil. It assumes be one of the following values:

'same'

Dil has the same size as the original image, M x N. The image is assumed to be 0 outside its bounds.

'full'

Dil contains the full dilation, (M+2*radius-1) x (N+2*radius-1). The image is assumed to be 0 outside its bounds.

DESCRIPTION

Function edilate performs exact euclidean dilation of a binary image Img using a circle as the structuring element. It is implemented in C to be fast.

EXAMPLE

Img = gray_imread(SIPDIR+'images/tru.jpg');
Img = 1-im2bw(Img, 0.3);
xbasc()
imshow(Img,2);
e = edilate(Img,7);
xbasc()
imshow(e,2);
