|a Multi-oriented and multi-lingual scene text detection plays an important role in computer vision area and is challenging due to the wide variety of text and background. In this paper, firstly we point out the two key tasks when extending CNN based object detection frameworks to scene text detection. The first task is to localize the text region by a down-sampled segmentation based module, and the second task is to regress the boundaries of text region determined by the first task. Secondly, we propose a scene text detection framework based on fully convolutional network (FCN) with a bi-task prediction module in which one is pixel-wise classification between text and non-text, and the other is pixel-wise regression to determine the vertex coordinates of quadrilateral text boundaries. Post-processing for word-level detection is based on Non-Maximum Suppression (NMS), and for line-level detection we design a heuristic line segments grouping method to localize long text lines. We evaluated the proposed framework on various benchmarks including multi-oriented and multi-lingual scene text datasets, and achieved state-of-the-art performance on most of them. We also provide abundant ablation experiments to analyze several key factors in building high performance CNN based scene text detection systems
