Web•Gatos - "Adaptive degraded document image binarization", 2005. (Partial) •NICK - "Comparison of Niblack inspired Binarization methods for ancient documents", 2009. WebThis paper presents a new adaptive approach for the binarization and enhancement of degraded documents. The proposed method does not require any parameter tuning by the user and can deal with degradations which occur due to shadows, non-uniform illumination, low contrast, large signal-dependent noise, smear and strain.
Novel Adaptive Binarization Method for Degraded Document Images
WebMar 16, 2024 · Generally, binarization methods are ineffective for degraded images. Several binarization methods have been proposed; however, none of them are effective … WebShadow detection and removal is an important task for digitized document applications. It is hard for many methods to distinguish shadow from printed text due to the high darkness similarity. In this paper, we propose a local water-filling method to remove shadows by mapping a document image into a structure of topographic surface. Firstly, we design a … dairy related words

WebDocument image binarization is an important pre-processing technique for document image analysis that segments the text from the document image back-grounds. Many techniques have been proposed and successfully applied in different applications, such as document image retrieval. However, these techniques may perform poorly on … WebMay 10, 2024 · Unlike global approaches, the local adaptive document image binarization [7], [1] determine the threshold for each pixel adaptively, which can behave better than global methods on degraded and broken document images. Adaptive binarization can also reduce noise while segmenting text from background. WebAug 1, 2024 · For degraded document images, adaptive binarization methods often incorporate local information to determine the binarization threshold for each individual pixel in the document image. dairy related jobs
