edilate

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.

Parameters

Dil

Resultant image.

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.

Examples

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