Hu invariant moments have been widely used in pattern recognition applications. In Digital Rock Physics applications several analysis are evaluated in different scales and an integrated approach is needed. In the current work, we present a study of microtomographic images from geological plugs and discuss a simple algorithm to match shapes in different scales. One analyze the efficiency of the matching algorithm comparing patterns obtained in high resolution images with its lower resolution version, and also with noise added.
