Hi i am using matlab 2010a for image processing of fracture images. But i find it difficult to extract features(variance ,smoothness,entropy) from the image? Is it possible to use a generate function call for extracting texture features from such an image?

Yes. You write it like any other function. You need to do image analysis to measure whatever you need, such as area, total crack length, average width, number of branchpoints, or whatever. Then string them all together into a vector - that's your "feature vector". See my File Exchagne for demos on image analysis.

Yes, you can use var() or entropyfile(). Attached are some more demos.
