Problems solved by technology

The traditional image processing technology is to filter the stamp through the separation of color channels, but the color of the stamp in the actual scene is often similar to the color of the bill text, and the stamp is not simply presented in one color due to the influence of the environment. Therefore, the traditional image processing method is used. It will lead to inaccurate stamp removal, for example, stamp removal is not clean or non-stamp information is also removed

Abstract

The embodiment of the invention provides an image processing method and device, electronic equipment and a computer readable storage medium, and relates to the field of image processing. The method comprises the following steps: graying and binarizing an initial image containing a seal to obtain a corresponding binary image, classifying each pixel point of the binary image based on an image segmentation model to obtain a corresponding classification result, and finally mapping the classification result into a corresponding pixel value to obtain an image not containing the seal. According to the embodiment of the invention, each pixel point is classified according to the image features, the method is not sensitive to the pattern, color and shielding condition of the seal, and the seal in the image can be removed more accurately.

Description

technical field [0001] The present application relates to the field of image processing, and in particular, the present application relates to an image processing method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] At present, people often use OCR technology to process bills. OCR technology can locate the text area of ​​the bill picture, and recognize the text content, extract useful information in the bill, and improve the speed of bill processing. However, there are often seals on the key information on the bill, which will cause difficulties in the positioning of the text area and character recognition, resulting in failure to extract the bill information. [0003] Therefore, before performing OCR recognition, it is necessary to remove the stamp. The traditional image processing technology is to filter the stamp through the separation of color channels, but the color of the stamp in the actual scene is often similar t...
