Compute the standard deviation of the input image.
function call:
[num1]=vsg('STDCalc',in_img1);
Arguments:
in_img1
input image, 3
channel RGB, 1 channel greyscale or binary image, or DICOM image.
Description:
num1
– a double representing the greyscale intensity standard deviation of
in_img1.
Example:
img = openimage('lake.jpg');
[num1]=vsg('STDCalc',img)
num1 = 65.4649
Notes:
1. For DICOM images, the function calculates the std value across all
slices
2. For RGB images, the function calculates the std value across all
colour planes.
