Abstract

The embodiment of the invention provides an image processing method and device, equipment and a medium, and the method comprises the steps: carrying out feature extraction of a to-be-processed image,and obtaining a feature map of the to-be-processed image; determining an attribute prediction value of each feature point on the feature map, wherein the attribute prediction value of one feature point represents the probability that a pixel point corresponding to the feature point in the to-be-processed image belongs to a text region, the prediction distance between the pixel point and a plurality of position points of the text region to which the pixel point belongs, and the prediction category of the text region to which the pixel point belongs; and according to the attribute prediction value of each feature point on the feature map, marking the position and category of each text region on the to-be-processed image. By adopting the technical scheme of the invention, the accuracy of positioning and classifying the text area in the image can be improved.

Description

technical field

[0001] The present invention relates to the technical field of image processing, in particular to an image processing method, device, equipment and medium. Background technique

[0002] In the field of Optical Character Recognition (OCR, Optical Character Recognition), a commonly encountered scenario is that it is necessary to perform text processing on a fixed template certificate (such as an ID card, driver's license, car purchase invoice, etc.) Identification of content. When identifying the text content of images with fixed templates, it is usually necessary to locate the target text area that needs to be identified (such as the name, gender, ethnicity, etc. on the ID card), that is, to mark each target text area in the image In order to output the recognition result of each text area to the user.

[0003] When locating a text area, in the related art, generally, the content in the image is firstly matched with keywords to classify and locate the text a...

Embodiment Construction

[0030] In order to make the above objects, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described implementation Examples are some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] In related technologies, the following two methods are generally used when locating and classifying text domains in images of fixed template classes:

[0032] One way is to identify the content of the detected text lines, and finally classify these text lines into text domains by means of text content keyword matching or the li...
