Assigns a unique value to each blob in the input image in a raster order.

 

function call:

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

 

Arguments:

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

 

Description:

out_img1 - An image which has dimensions the same as the input image. The output image displays individual blobs which have unique greyscale values for each blob.

 

Example:

img = imread('crown.jpg');

figure;image(img);

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

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

h=figure;imagesc(uint8(out_img1(:,:,1)));set(h,'Name','Lebelled Image');

 

Notes:

1. For DICOM images, the function operates on each slice separately.

2. For RGB images, the input on all 3 channels must be white for the area to be considered white.
