The embodiment of the present invention discloses a training method, device, device, and medium for detection and recognition and a detection and recognition network, wherein the detection and recognition method includes: inputting an image to be processed into the detection and recognition network; the detection and recognition network includes a shared network layer, Detection network layer and identification network layer; output the shared layer feature of the image to be processed through the shared network layer; input the shared layer feature into the detection network layer, output the image to be processed through the detection network layer The detection layer feature, based on the detection layer feature, obtains the text box information including text in the image to be processed; the shared layer feature and text box information are input into the recognition network layer, and the recognition network layer outputs all The text content in the description text box. The embodiment of the present invention reduces repeated feature extraction of images, improves processing efficiency, and improves the efficiency and speed of character detection and recognition.
Description
technical field [0001] The invention relates to computer vision technology, in particular to a training method, device, equipment and medium for detection and recognition and detection and recognition networks. Background technique [0002] Text detection and recognition in natural scenes is an important problem in the field of image understanding and image restoration. Accurate text detection and recognition can be used for many problems, such as image search under large data sets, automatic translation, guidance for the blind, robot navigation, etc. [0003] However, text detection and recognition in natural scenes is very challenging. Factors such as different background scenes, low resolution, different fonts, different lighting conditions, different sizes, different tilt directions, and blur all make this problem become very complex and difficult. Contents of the invention [0004] An embodiment of the present invention provides a technical solution for character re...
