Multilingual Text Detection with Nonlinear Neural Network

Abstract EN

Multilingual text detection in natural scenes is still a challenging task in computer vision.

In this paper, we apply an unsupervised learning algorithm to learn language-independent stroke feature and combine unsupervised stroke feature learning and automatically multilayer feature extraction to improve the representational power of text feature.

We also develop a novel nonlinear network based on traditional Convolutional Neural Network that is able to detect multilingual text regions in the images.

The proposed method is evaluated on standard benchmarks and multilingual dataset and demonstrates improvement over the previous work.
