Morphological Gradient (user specify connectivity of the structured element 6 or 26) [Default=6].

 

function call:

[out_img1]=vsg('BeucherGrad3D',in_img1,connected);

 

Arguments:

in_img1 -  input image, a DICOM image.

connected – an integer specifying whether 6 or 26 connected is used.

 

Description:

out_img1 – a DICOM image. Each value of the DICOM image is the result of subtracting a 3D eroded input image from a 3D dilated input image. DICOM data must be in a separate folder.

 

Example:

[filename, chosenDirectory] = uigetfile('*.dcm', 'Pick an M-file');

filePath = [chosenDirectory filename];

stackOfImages=vsg('DICOMRead',filePath);  %4D array of data

[out_img1]=vsg('BeucherGrad3D',stackOfImages,8);

 

Notes:

1. For RGB or Dicom images, the function operates on all colour planes or slices separately.

2. Dicom images require XMedCon software (version xmedcon-0.10.5-1-win32).

3. DICOM data must be in a separate folder.
