In this chapter, we propose a novel junction detection method in handwritten images, which uses the stroke-length distribution in every direction around a reference point inside the ink of texts. Our proposed junction detection method is simple and efficient, and yields a junction feature in a natural manner, which can be considered as a local descriptor. We apply our proposed junction detector...

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 Examples of degraded document collections include historical document depositories, document obtained in legal and security investigations, and legal and medical archives.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Historical documents contain facts that family history enthusiasts are interested in extracting.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.

The EPC (Engineering Procurement Construction) industry is one of the most dynamic industries. problems faced are related to market conditions that often change, short construction periods, and fluctuations in material prices difficult predict. This requires an appropriate forecasting model, which can predict pattern price movements anticipate occurrence future. research aims get best during pr...

Abstract We describe a combination of methods applied to obtain reliable estimations of population density using archaeological data. The combination is based on a hierarchical model of scale levels. The necessary data and methods used to obtain the results are chosen so as to define transfer functions from one scale level to another. We apply our method to data sets from western Germany that c...
