Registration and Enhancement of Double-Sided Degraded Manuscripts Acquired in Multispectral Modality
13 years 2 months ago
We propose a system to process multispectral scans of double-sided documents. It can co-register any number of recto and verso channel maps, and reduce the bleed-through/show-thro...
