WebSep 12, 2016 · The CTPN detects a text line in a sequence of fine-scale text proposals directly in convolutional feature maps. We develop a vertical anchor mechanism that jointly predicts location and text/non-text score of each fixed-width proposal, considerably improving localization accuracy. VGG16提取的是空间特征，而LSTM学习的就是序列特征，而这里使用的是双向LSTM，更好的避免RNN当中的遗忘问题，更完整地提取出序列特征。 See more
