This tutorial will teach you how to train a custom OCR model for captcha image text extraction with TensorFlow and CTC Loss Function. You will learn how to install the necessary packages, download a dataset of captcha images and their corresponding labels, preprocess the dataset, and set up a data provider for training and validation. Then, you will learn how to define the model architecture, compile and train the model, and use the trained model to create a captcha-to-text solution. Finally, you will use the model to evaluate its performance on new captcha images. By the end of this tutorial, you will have a working captcha-to-text solution with TensorFlow and CTC Loss Function.
