WebNov 6, 2024 · I am using CTC in an LSTM-OCR setup and was previously using a CPU implementation (from here). I am now looking to using the CTCloss function in pytorch, however I have some issues making it work properly. My test model is very simple and consists of a single BI-LSTM layer followed by a single linear layer. def … WebMay 19, 2024 · 这几天闲的无聊看了一下有关于OCR方面的要点,主要还是详细了解基于CTPN+CRNN进行OCR检测。并且也看了内部代码,在这里想梳理一下论文要点以及代码逻辑。 首先给一下论文地址及代码地址: 1.论文地址:Detecting Text in Natural Image with Connectionist Text Proposal Network
