Abstract

The invention relates to the technical field of image processing, and specifically provides an image watermark removal device, aiming at solving the technical problems of how to improve the picture quality of restored images and the accuracy of face verification. For this purpose, the image watermark removal device in the present invention can perform dewatermark processing on the face image based on the confrontation generation network model, wherein, the generator in the confrontation generation network model can generate a corresponding watermark-free image based on the face image, and distinguish The generator can judge whether the whole image and partial image of the image without watermark are real images, and the optimization module optimizes the generator and the discriminator. Furthermore, the device may also include a face recognition model to extract the face features of the original image without watermark and the image without watermark generated by the generator, and further optimize the generator and discriminator. The technical scheme of the invention can effectively protect the information contained in the image while acquiring a high-quality image without a watermark.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image watermark removal device. Background technique [0002] Witness comparison refers to the verification of a person's identity by comparing the person's ID photo with the photos taken on the spot. In some occasions, for the consideration of user privacy, watermarks are often added to ID photos. Although the convolutional neural network has made a great breakthrough in face recognition, the watermark on the ID photo will block the face, resulting in a significant reduction in the accuracy of witness comparison. The traditional method is to train a fully convolutional network to remove the watermark of the ID photo. However, this method will lose part of the identity information of the ID photo while removing the watermark, and the recovered face is close to the average face, resulting in low accuracy of witness comparison.
