Edge-Preserving Cross-Sharpening of Multi-Modal Images
Yu Qiu, Kiichi Urahama · IEICE Transactions on Information and Systems · 2011
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 UM is then extended to cross-sharpening of multi-modal images where a component image is sharpened with the aid of more clear edges in another component image.
