Displaying Images after feature extraction
Show older comments
I have a image and have extracted texture features
g=rgb2gray(g);
glcm=graycomatrix(g);
F=graycoprops(glcm,'Contrast','Homogeneity','Correlation','Energy'});
contrast=F.Contrast;
homogeneity=F.Homogeneity;
correlation=F.Correlation;
energy=F.Energy;
now how to display the image as below
in result i have res=[contrast energy homogeneity]
based upon the feature exracted feature result please tell how to apply kmeans on images

If you have four images in I, J, K and L, you could do this,
figure
subplot(2,2,1); imshow(I)
subplot(2,2,2); imshow(J)
subplot(2,2,3); imshow(K)
subplot(2,2,4); imshow(L)
As for kmeans, http://openclassroom.stanford.edu/MainFolder/DocumentPage.php?course=MachineLearning&doc=exercises/ex9/ex9.html may be a good resource to start with.

So what? Your image just had 4 pictures with titles. If you want numbers to be in the title you can do that.
caption = sprintf('Contrast = %.1f', contrast);
title(caption, 'FontSize', 24);

images are displayed with imshow().
imshow(yourImage);
Text is displayed with set(), text(), fprintf(), etc.
fprintf('The energy = %.2f', energy);
set(handleToStaticText, 'String', 'Blah blah blah');
I don't know what you consider an energy diagram. Perhaps it's a matrix so you can display with imshow:
imshow(myEnergyDiagram, []);

Did you see the middle part of my comment above, where I showed you how to display a number as a text label on your GUI or in the command window? P.S., to make it easier on us, you might use Firefox, which has a spell checker built into it. Please proofread your comments because all too frequently they don't make sense:
vale
noun
1. a valley.
2. the world, or mortal or earthly life: this vale of tears.
