Research output: Contribution to journalArticlepeer-review


We present a simple technique for enhancing multi-modal images. The unsharp masking (UM) is at first nonlinearized to prevent halos around large edges. This edge-preserving UMis then extended to crosssharpening of multi-modal images where a component image is sharpened with the aid of more clear edges in another component image.
