Robust document image binarization technique for degraded document images

B Su, S Lu, CL Tan - IEEE transactions on image processing, 2012 - ieeexplore.ieee.org
Segmentation of text from badly degraded document images is a very challenging task due
to the high inter/intra-variation between the document background and the foreground text of …

Binarization of historical document images using the local maximum and minimum

B Su, S Lu, CL Tan - Proceedings of the 9th IAPR International …, 2010 - dl.acm.org
This paper presents a new document image binarization technique that segments the text
from badly degraded historical document images. The proposed technique makes use of the …

Document image binarization using background estimation and stroke edges

S Lu, B Su, CL Tan - International Journal on Document Analysis and …, 2010 - Springer
Document images often suffer from different types of degradation that renders the document
image binarization a challenging task. This paper presents a document image binarization …

Accurate scene text recognition based on recurrent neural network

B Su, S Lu - Computer Vision–ACCV 2014: 12th Asian Conference …, 2015 - Springer
Scene text recognition is a useful but very challenging task due to uncontrolled condition of
text in natural scenes. This paper presents a novel approach to recognize text in scene …

Blurred image region detection and classification

B Su, S Lu, CL Tan - Proceedings of the 19th ACM international …, 2011 - dl.acm.org
Many digital images contain blurred regions which are caused by motion or defocus.
Automatic detection and classification of blurred image regions are very important for different …

Accurate recognition of words in scenes without character segmentation using recurrent neural network

B Su, S Lu - Pattern Recognition, 2017 - Elsevier
Recognition of texts in scenes is one of the most important tasks in many computer vision
applications. Though different scene text recognition techniques have been developed, scene …

Multilingual scene character recognition with co-occurrence of histogram of oriented gradients

S Tian, U Bhattacharya, S Lu, B Su, Q Wang, X Wei… - Pattern Recognition, 2016 - Elsevier
Automatic machine reading of texts in scenes is largely restricted by the poor character
recognition accuracy. In this paper, we extend the Histogram of Oriented Gradient (HOG) and …

Combination of document image binarization techniques

B Su, S Lu, CL Tan - 2011 International Conference on …, 2011 - ieeexplore.ieee.org
Document image binarization has been studied for decades, and many practical binarization
techniques have been proposed for different kinds of document images. However, many …

Scene text recognition using co-occurrence of histogram of oriented gradients

S Tian, S Lu, B Su, CL Tan - 2013 12th International …, 2013 - ieeexplore.ieee.org
Scene text recognition is a fundamental step in End-to-End applications where traditional
optical character recognition (OCR) systems often fail to produce satisfactory results. This …

A new gradient based character segmentation method for video text recognition

P Shivakumara, S Bhowmick, B Su… - … on document analysis …, 2011 - ieeexplore.ieee.org
The current OCR cannot segment words and characters from video images due to complex
background as well as low resolution of video images. To have better accuracy, this paper …
