Abstract

The invention relates to the technical field of image processing, in particular to an image watermark removal device. The image watermark removal device aims to provide a way of solving the technicalproblem that the picture quality of a restored image and face verification accuracy are low. In order to realize the purpose, the image watermark removal device can carry out watermark removal processing on a face image on the basis of a generative adversarial network model, wherein a generator in the generative adversarial network model can generate a corresponding watermark-free image corresponding to the face image, a discriminator can judge whether the integral image and the local image of the watermark-free image are true images or not; and an optimization module optimizes the generator and the discriminator. Furthermore, the device comprises a face recognition model to extract the face feature of a watermark-free original image and the face feature of the watermark-free image generated by the generator, and the generator and the discriminator are further optimized. By use of the technical scheme of the invention, while the high-quality watermark-free image can be obtained, information contained in the image is effectively protected.

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. Contents of the invention [0003] In...
