Summary: | Scene text detection is currently a popular research topic in the computer vision community. However, it is a challenging task due to the variations of texts and clutter backgrounds. In this paper, we propose a novel framework for scene text localization. Based on the region proposal network, a Strip-based Text Detection Network (STDN) is developed with vertical anchor mechanism to predict the text/non-text strip-shaped proposals. Meanwhile, we incorporate the recurrent neural network layers in the proposed network to refine the predicted results. Specifically, hard example mining is performed to train the STDN with cascade learning, which has a remarkable improvement in precision. Besides, we exploit a clustering algorithm to generate anchor dimensions spontaneously without hand-picking, which is portable and time-saving. The text detection framework achieves the state-of-the-art performance on ICDAR2013 with 0.89 F-measure. |
