NAME

erode - morphological erosion of binary images

SYNOPSIS

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

PARAMETERS

Img
M x N Binary image to be eroded. (0 for background, 1 for object)
E
M x N Binary eroded image.
SE
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 erode performs morphological erosion of a binary image Img using SE as the structuring element.

EXAMPLE

initial_dir = PWD;
chdir (SIPDIR + 'images');

Img = gray_imread('disks2.bmp');
imshow(Img,2);
Img = 1-Img;
SE = ones(10,10);
e = erode(Img, SE);
xbasc()
imshow(e ,2);

chdir(initial_dir);

REMARKS

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