Compute the skewness deviation of the input image.
function call:
[num1]=vsg('SkewCalc',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 skewness of
in_img1.
Example:
img = openimage('lake.jpg');
[num1]=vsg('SkewCalc',img)
num1 =
0.6827
Notes:
1. For DICOM images, the function calculates the skewness value across
all slices
2. For RGB images, the function calculates the skewness value across all
colour planes.
