Label the unconnected shapes in a binary image in relation to their size.

 

function call:

[out_img1]=vsg('LabelByVol',in_img1);

 

Arguments:

in_img1 - input image, a DICOM image which is binary, i.e. with values 0 or 255;

 

Description:

out_img1 – a DICOM image. The input image is processed such that each connected region is given an individual label. These labels are then re-ordered such that the largest blob will have the lowest label and the smallest blob, the highest label. The output image is an image of these labels;

 

Example:

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

filePath = [chosenDirectory filename];

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

[out_img1]=vsg('Threshold',stackOfImages,500);

[out_img1]=vsg('LabelByVol',out_img1);

 

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.
