Abstract

The invention relates to a natural scene text detection method based on an attention mechanism convolutional neural network. Firstly, image data with text under natural scene is labeled and divided into training set and test set. Then the text image is processed as training data by data enhancement method. Based on the attention mechanism module and Inception network, a feature extraction networkis constructed, and the features of different fonts are learned by multi-scale feature fusion. The network is pre-trained using course learning strategies. The network is trained again by using the text image data of the natural scene. The fused features are adopted to regress to get the coordinates of the text in the image, and the text detection results are obtained. Finally, the validity of thetrained neural network is verified in the test set and other open data sets. The method can solve the problems of low character recall rate and low recognition accuracy under complex natural environment in the current technology, and has advantages in running speed.

Description

technical field [0001] The invention relates to the fields of pattern recognition and computer vision, in particular to a natural scene text detection method based on an attention mechanism convolutional neural network. Background technique [0002] As one of the main carriers of information transmission in people's life, text plays an extremely important role in real life. Automatic text detection provides a method for computers to obtain text information by using pictures and videos, making it possible to quickly and automatically process text information in massive natural scenes. [0003] Difficulties in automatic text detection in natural scenes include: [0004] (1) The characters in the text are of different sizes. [0005] (2) There are various fonts in the text. [0006] (3) Texts in natural scenes have complex image backgrounds. [0007] (4) Observing the text from different perspectives. [0008] (5) Diversity of illuminance. [0009] Existing research has p...
