ICFHR - An Effective Binarization Method for Disturbed Camera-Captured Document Images
2018 16th International Conference on Frontiers in Handwriting Recognition (ICFHR), 2018Co-Authors: Jinyuan Zhao, Yanna Wang, Baihua XiaoAbstract:Many researchers make numerous work on document image binarization. However, the binarization results of camera-captured document images remain to be improved due to many disturbances such as creases, noises and shadows. To binarize these images effectively, this paper proposes an adaptive local thresholding method which takes advantages of multi-level multi-scale local statistical information. By using the context information of multiple scales, the pixels in the image are classified by coarse to fine. The majority of background areas were removed by multiscale analysis of variance. For the text area, the binarization threshold is dynamically adjusted according to the estimated clarity. Our method can make the grayscale image binarization directly, without adding any Postprocessing Operation. The experimental results show that our method can significantly improve the performance of OCR system and is also suitable for degraded document images

A Reply to Comments on “New Algorithm for Measuring 50/60 Hz AC Values Based on the Usage of Slow A/D Converters” and “Measuring of Slowly Changing AC Signals Without Sample-and-Hold Circuit”
IEEE Transactions on Instrumentation and Measurement, 2006Co-Authors: P. Petrovic, M. StevanovicAbstract:This reply comments on the results and conclusions of the above paper. The authors analyze the proposed numerical method (the trapezoidal rule) for numerical integration as well as the possible sources of error in this type of processing, and derive analytical expression for them. In addition, the authors provide comments on the principle of signal reconstruction proposed in the above paper and show that the Postprocessing Operation is not necessary. It has been presented that no doubts exist in the experimental results given in the commented papers, with an accuracy of 0.01%
