In contrast to most existing works that consist of multiple deep neural networks and several pre-processing steps we propose to use a single deep neural network that learns to detect and recognize text from natural images in a semi-supervised way. 想要学习场景文本识别的相关技术,从原理到实践都想要掌握,有没有专门关于ctpn的推荐书籍啊? 是text detection / text. If you use CUDNN, about 1. 发现了一篇最新的文章,里面的方法可以检测任意方向的文字,准确率较CTPN方法增加了一个数量级,这个方法但是没有开源的实现,论文放在了paper文件夹下,1802. The competition received a total of.
