Thread Subject:
Texture Feature Extraction using GLCM

Subject: Texture Feature Extraction using GLCM

I'm doing a project in liver tumor classification. I used the program at

http://www.mathworks.com/matlabcentral/fileexchange/22187-glcm-texture-features/content/GLCM_Features1.m

and it gave some output. I don't know whether I'm correct.

Actually I initially used Region Growing method for liver segmentation and from that I segmented tumor using FCM. So, to this GLCM program, I gave the tumor segmented image as input. Was I correct? If so, I think, then, my output will also be correct.

I gave the parameters exactly as in the example. Actually what do they mean? Do I need to change them for different images? If so, how to give the parameters? I'm completely new to this. So, kindly guide me.

I got this output. Am I correct?
