Plane Geometry Diagram Parsing
Ming-Liang Zhang, Fei Yin, Yi-Han Hao +1
Geometry diagram parsing plays a key role in geometry problem solving, wherein the primitive extraction and relation parsing remain challenging due to the complex layout and betwee…
Document Dewarping with Control Points
Guo-Wang Xie, Fei Yin, Xu-Yao Zhang +1
Document images are now widely captured by handheld devices such as mobile phones. The OCR performance on these images are largely affected due to geometric distortion of the docum…
Emergence of Machine Language: Towards Symbolic Intelligence with Neural Networks
Yuqi Wang, Xu-Yao Zhang, Cheng-Lin Liu +1
Representation is a core issue in artificial intelligence. Humans use discrete language to communicate and learn from each other, while machines use continuous features (like vecto…
Dewarping Document Image By Displacement Flow Estimation with Fully Convolutional Network
Guo-Wang Xie, Fei Yin, Xu-Yao Zhang +1
As camera-based documents are increasingly used, the rectification of distorted document images becomes a need to improve the recognition performance. In this paper, we propose a n…
Weakly-Supervised Arbitrary-Shaped Text Detection with Expectation-Maximization Algorithm
Mengbiao Zhao, Wei Feng, Fei Yin +2
Arbitrary-shaped text detection is an important and challenging task in computer vision. Most existing methods require heavy data labeling efforts to produce polygon-level text reg…
Towards Robust Pattern Recognition: A Review
Xu-Yao Zhang, Cheng-Lin Liu, Ching Y. Suen
The accuracies for many pattern recognition tasks have increased rapidly year by year, achieving or even outperforming human performance. From the perspective of accuracy, pattern…
