Abstract

The invention provides an image decontamination method and device, a readable storage medium and computer equipment, and the method comprises the steps: obtaining an original image, adjusting the sizeof the original image to a threshold size, and obtaining a first processed image; utilizing the trained generative adversarial network model to carry out decontamination processing on the first processing image to obtain a second processing image; performing structural similarity calculation on the first processed image and the second processed image to obtain a difference feature map between thefirst processed image and the second processed image; comparing the difference feature map with the first processing image to determine a stain area in the first processing image and position information of the stain area; zooming the stain area to a size corresponding to the original image, and determining a target stain area in the original image according to the zoomed stain area and the position information; and removing the content of the target stain area in the original image.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an image decontamination method, device, readable storage medium and computer equipment. Background technique [0002] In the fields of digital archiving, education and other fields, it is often necessary to repeatedly print the contents of paper documents, generally by scanning and copying. However, if the surface of the paper document is not clean or the surface is uneven or rough, many stained areas (such as large black spots, gathered scattered spots, etc.) will appear after the document is scanned or copied, which will affect the use. Therefore, it is often necessary to desmear the image. [0003] The traditional method of removing stains from scanned images is to perform distance transformation on the binarized image to obtain a number of image blocks, and then perform connected region analysis to obtain a rectangular frame surrounding the image blocks, and analyze the...
