A Restoration and Segmentation Unit for the Historic Persian Documents

2005
This paper aims to provide a document restoration and segmentation algorithm for the Historic Middle Persian or Pahlavi manuscripts. The proposed algorithm uses the mathematical morphology and connected component concept to segment the line, word, and character overlapped in the Middle-age Persian documents in preparation for OCR application.

A method for restoration of low-resolution document images

International Journal on Document Analysis and Recognition, 2000
Image restoration using resolution expansion is important in many areas of image processing. This paper introduces a restoration method for low-resolution text images which produces expanded images with improved definition. This technique creates a strongly bimodal image with smooth regions in both the foreground and background, while allowing for ...

Restoration of Audio Documents by Means of Extended Kalman Filter

IEEE Transactions on Audio, Speech, and Language Processing, 2010
We present some results on audio restoration obtained with an algorithm that solves the problems of broadband noise filtering, signal parameters tracking, and impulsive noise removal by using the Extended Kalman Filter (EKF) theory. We show that, to achieve maximum performance, it is essential to optimize the EKF implementation. To this purpose, having

Self-Embedding and Restoration Algorithms for Document Watermark

Proceedings. (ICASSP '05). IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005., 2006
When a document or a sequence of characters is tampered, watermarking should be able to not only detect the tampering but also restore it. Towards this goal, self-embedding is used where the watermark is a copy of the sequence itself. Restoration algorithms for substitution attack are proposed for two variants of self-embedding.

Document: Architecture and Monument Restoration (1967)

Future Anterior, 2009
This essay, the third and last of a series of lectures delivered at Colegio Nacional in Mexico City in 1966, laid out what Villagran described as an "authentic theory of monument restoration," which upheld the importance of subjective creativity against the myth of objectivity inherent in the prevailing "zealous" archeological formulas to preserve ...
