Single threshold operation: threshold level = MIDGREY (127).

 

function call:

[out_img1]=vsg('MidThresh',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 pixel values are white if they are larger than or equal to 127, otherwise they are black.

 

Example:

img = openimage('crown.jpg');

h=figure;image(uint8(img));set(h,'Name','Input Image');

[out_img1]=vsg('MidThresh',img);

h=figure;image(uint8(out_img1));set(h,'Name','MidThresh');

 

Notes:

1. For DICOM images, the function operates on all slices separately.

2. For RGB images, the function operates on all colour planes separately.
