Abstract
Scene text detection and recognition are important tasks. However, scene text detection and recognition in real world images is one of the most challenging tasks in text mining. This paper focuses on one of the scene text detection and recognition applications, electrical meter reading. For this purpose, we propose a two-step model. First, a detection method is adapted to detect digit regions. Then, an end-to-end neural network is used, which is a combination of convolutional neural networks (CNNs), recurrent neural networks (RNNs), and connectionist temporal classification (CTC) loss. The convolutional part pulls out important features, while the RNN part encodes and decodes sequences of features. Moreover, we gather a large dataset of meter devices whose numbers are in Persian. In order to evaluate our model, we compare it with different architectures and models. The analysis of the results shows that our model achieves higher accuracy and outperforms the baseline approaches.
