Degraded documents are frequently obtained in various situations. Examples of degraded document collections include historical document depositories, document obtained in legal and security investigations, and legal and medical archives. Degraded document images are hard to to read and are hard to analyze using computerized techniques. There is hence a need for systems that are capable of enhan...

We present an interactive method to restore severely damaged historical parchments. When damaged by heat in a fire, such manuscripts undergo a complex deformation and contain various geometric distortions such as wrinkling, buckling, and shrinking, rendering them nearly illegible. They cannot be physically flattened due to the risk of further damage. We propose a virtual restoration framework t...

Historical documents contain facts that family history enthusiasts are interested in extracting. In addition to fact extraction, organizing these facts into disambiguated entity records is also of interest. This paper shows how facts from an excerpt of a page in an OCRed book can be gathered automatically with some expert knowledge.

4 Empirical Orthogonal Function (EOF) Analysis is commonly used in the climate sciences 5 and elsewhere to describe, reconstruct, and predict highly dimensional data fields. When 6 data contain a high percentage of missing values (i.e. “gappy”), alternate approaches must 7 be used in order to correctly derive EOFs. The aims of this paper are to assess the accuracy 8 of several EOF approaches in...

T he theory of rings has deep historical roots in several of the mainstream, classical disciplines of nineteenth-century mathematics, such as the theory of algebraic number fields, the theory of algebraic functions, the theory of polynomial forms, the theory of quaternions and hypercomplex numbers, and others. The unification of all these trends reached its peak with the works of Emmy Noether (...
