Why is this code not working and returns
('error' .... out = features_calc(GLCMS,{'autoc','dissi','cshad','entro'}), Undefined function or variable 'features_calc'.
Can any one help me in correcting this codes? I need to calculate and display all haralick features,please
I=dicomread('mri.dcm');
k=rgb2gray(I);
h = uint8(k);
offsets=[0 1;-1 1;-1 0;-1 -1; 1 1; 0 -1; 1 -1; 1 0];
[GLCMS,SI] =graycomatrix(h,'Offset',offsets);
out = features_calc(GLCMS,{'autoc','dissi','cshad','entro'});
g1 =out.outoc;
g2 =out.diss;
g3 =out.cshad;
g4=out.entro;
out=('autoc dissi cshad entro');
figure,imshow(g1);
figure,imshow(g2);
figure,imshow(g3);

Hi Eten,
To calculate and display certain Haralick features from a DICOM image, you can use the ‘graycoprops’ function in MATLAB and compute some standard Haralick features that are available such as Contrast, Correlation, Energy and Homogeneity.
% Haralick features using graycoprops
stats = graycoprops(GLCMS, {'Contrast', 'Correlation', 'Energy', 'Homogeneity'});
% Display the features
fprintf('Contrast: %f\n', stats.Contrast);
fprintf('Correlation: %f\n', stats.Correlation);
fprintf('Energy: %f\n', stats.Energy);
fprintf('Homogeneity: %f\n', stats.Homogeneity);
To know more about the ‘graycoprops’ function, you can refer the following page:
Hope this works for you!
