How to determine texture of a skin lesion?

I have used a gray scale image without segmentation and with segmentation and got different result of 'contrast', 'energy','homogeneity', and 'correlation'. I used this code:

glcms = graycomatrix(t1) %t1 is a gray image

stats = graycoprops(glcms,'contrast','energy')

stats2=graycoprops(glcms,'homogeneity','correlation')

The images are:

How can I know which image will give accurate answer?
