Robust Line Detection in Historical Church Registers
نویسندگان
چکیده
For being able to automatically acquire information recorded in church registers and other historical scriptures, the text of such documents needs to be segmented prior to automatic reading. Segmentation of old handwritten scriptures is difficult for two main reasons. Lines of text in general are not straight and ascenders and descenders of adjacent lines interfere. The algorithms described in this paper provide ways to reconstruct the path of the lines of text using an approach of gradually constructing line segments until an unique line of text is formed. The method was applied to church registers. They were written by different people in different styles between the 17th and 19th century. Line segmentation was found to be successful in 95% of all samples.

Line Detection and Segmentation in Historical Church Registers
For being able to automatically acquire the information recorded in church registers and other historical scriptures, the writing on these documents has to be recognized. This paper describes algorithms for transforming the paper documents into a representation of text apt to be used as input for an automatic text recognizer. The automatic recognition of old handwritten scriptures is difficult ...
متن کاملSegmentation of the Date in Entries of Historical Church Registers
Handwriting recognition requires a prior segmentation of text lines which is a challenging task, especially for historical scripts. Exemplary for the date in entries of historical church registers, we present an approach which enables a segmentation by using additional knowledge about the word sequence. The algorithm is based on probability distribution curves and a neural network, which assess...
متن کاملDyVSoR: dynamic malware detection based on extracting patterns from value sets of registers
To control the exponential growth of malware files, security analysts pursue dynamic approaches that automatically identify and analyze malicious software samples. Obfuscation and polymorphism employed by malwares make it difficult for signature-based systems to detect sophisticated malware files. The dynamic analysis or run-time behavior provides a better technique to identify the threat. In t...
متن کاملEditing the Past: Cosmo Innes and the Scottish Medieval Church
In 1832 the Maitland Club published an edition of the register of Paisley Abbey, a sixteenth century manuscript detailing, through transcripts of original charters and other documents, the institution’s property and privileges. This publication was the first of its kind in Scotland and was the work of the lawyer, historian and record scholar Cosmo Innes (17981874). He went on to edit a further ...
متن کاملA methodology for robust fault detection in dynamic systems
This paper is concerned with the robust detection of abnormalities occurring in complex operations such as those found in industrial processes. A methodology for detection of process abnormalities is presented which uses only uncertain dynamic process models derived from historical operational data and little !a priori fault information. The emphasis of the methodology is to provide a robust, o...
