Abstract: The text recognition method includes: acquiring a first high-frequency feature map and a first low-frequency feature map of a target image; performing an M-level convolution process on the first high-frequency feature map and the first low-frequency feature map by M cascaded convolution modules to obtain M pairs of target high-frequency feature map and target low-frequency feature map of the target image, where M is a positive integer; merging the M pairs of target high-frequency feature map and target low-frequency feature map to obtain a target feature map of the target image; determining a probability map and a threshold map of the target image based on the target feature map, and calculating a binarization map of the target image based on the probability map and the threshold map; and determining a text area in the target image based on the binarization map, and recognizing text information in the text area.
