BiggestBlob

Extract the biggest white blob from a binary image.

 

function call:

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

 

Arguments:

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

 

Description:

Find the largest, non-connecting, white blob in a binary image. out_img1 - an image which has dimensions the same as the input image. The output image displays the largest of the input white blobs.

 

Example:

img1 = openimage('blobs.bmp');

h=figure;image(img1);set(h,'Name','Input Image');

[out_img1]=vsg('Threshold',img1,100);

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

h=figure;image(uint8(out_img1));set(h,'Name','Biggest Blob 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.
