[0047] In order to describe the specific implementation of the present invention in detail, a character detection data set is taken as an example. The dataset contains 250 natural scene images containing text as a training set and 249 as a test set. The implemented model can automatically detect text inside images. Specific steps are as follows:
[0048] Step S1, cut out 5980 character images from the data set as a training set, and 5198 character images form a test set.
[0049] Step S2, use a 2-layer convolutional layer + 3-layer fully connected layer deep convolutional neural network for learning, the first convolutional layer uses 64 feature maps, a 9×9 convolutional window, and the second convolutional layer Using 64 feature maps, a 5×5 convolution window, and a convolution step size of 1. The number of nodes in the fully connected layer is 128, 128, and 62 respectively, such as figure 2 shown.
[0050] In step S3, the stochastic gradient descent method is adopted, ...
