Compute the energy of the co-occurrence matrix.
function call:
[num1]=vsg('CoEnergy',in_img1);
Arguments:
in_img1
input image, 3 channel
Description:
The CoEnergy
function calculates the energy of co-occurrence matrix of an image.
num1 – the energy of
the image used to create the input co-occurrence matrix image.
Returns the sum of squared elements in the
co-occurrence matrix.
Example:
img = openimage('lake.jpg');
h=figure;image(img);set(h,'Name','Input
Image');
[out_img1]=vsg('CoOcMatGen',img);
[num1]=vsg('CoEnergy',out_img1)
h=figure;imagesc((out_img1(:,:,1)));colormap(gray);set(h,'Name','CooccurrenceMatrixGenerator');
num1 = 19256891
Notes:
1. For DICOM images,
the function returns the mean energy per slice
2. For
