Multiresolution approach for image processing

1996

Multiresolution approaches provide a powerful tool for image process- ing. In this report,we propose an overview of different types of multiresolu- tion. We show this methodology is composed of two main complementary steps, the bottom-up and the top-down strategies. We also present some important existing applications like filtering and features extraction. Fi- nally, a brief comparison of the different techniques is given and some new interesting possible use of this tool are exhibited.
