Research on document digitization processing technology

DOCLIB : A Document Processing Research Tool

Often, valuable document processing intellectual capital is lost due to staff transitions or project restructuring prior to technology transfer. Furthermore, hardware and software integrity, dependencies, and compatibility are critical components that often impede technology migration. While many open source tools attempt to mitigate these issues, they do not always address specific design need...

Noisy Signal Processing Research based on Compressed Sensing Technology

Compressed sensing (CS) is a kind of sampling method based on signal sparse property, it can effectively extract the signal which was contained in the message. In this study, a new noise speech enhancement method was proposed based on CS process. Voice sparsity is used to this algorithm in the discrete fast Fourier transform (Fast Fourier transform, FFT), and observation matrix is designed in c...

document delivery service in the ministry of science, research and technology: an overview on its pitfalls and prospects

purpose: document delivery scheme for the libraries of the ministry of science, research and technology was launched in 1999 due to currency budget crisis. the main purpose of this paper is to investigate how the above document delivery service was launched, preformed and finally stopped. method: the current study applied questionnaire and interview surveys for studying different aspects of the...

Doctoral Dissertation Video Mosaicing Based on Structure from Motion for Geometric Distortion-Free Document Digitization

This thesis describes a novel video mosaicing method which is capable of generating a geometric distortion-free mosaic image. Video mosaicing, which stitches partial images of a target into a larger image called a mosaic image, has been used to obtain high resolution images of documents. Generally, mosaic images are prone to two types of geometric distortions: perspective distortion which appea...
