Input images (a) and separation results (b)–(f) of the Au/NiO dataset. The results were obtained with f1/2 set to either single filters or shallow DIPs. For each case, several γexcl values were tested. Ghost features are effectively suppressed with a proper setting for γexcl. However, when γexcl is too large, fine details of the features are smeared out. The final values of α1|α2 are indicated at the upper right corners of the corresponding subplots. The values of α hold steady except when we use shallow DIPs for f1/2 and over-weight the exclusion loss, in which case the ratio α1/α2 decreases significantly.
