Morphological Gradient (user specifies the connectivity of the structuring element - 4 or 8) [Default=8].

 

function call:

[out_img1]=vsg('BeucherGrad',in_img1,connected);

 

Arguments:

in_img1 mask image, 3 channel RGB, 1 channel greyscale or binary image, or DICOM image.

connected – an integer specifying whether 4 or 8 connected erosion should be carried out.

 

Description:

out_img1 – An image which has dimensions the same as the input image. This is the morphological gradient of the input image.

 

Example:

img = openimage('crown.jpg');

[out_img1]=vsg('Threshold',img,100);

[out_img2]=vsg('BeucherGrad',out_img1,8);

[out_img3]=vsg('BeucherGrad',img,8);

h=figure;image(uint8(out_img2));set(h,'Name','BeucherGrad - binary image');

h=figure;image(uint8(out_img3));set(h,'Name','BeucherGrad - Grey scale image');
