Résumé: Image super-resolution (SR) is an important image processing technique in computer vision. Although the convolutional neural network has developed rapidly and made some breakthroughs in the field of super-division, there are still some problems when images are magnified at large upscaling factors. Recently, generative adversarial network is popular, but the structural similarity (SSIM) between the super-resolution (SR) image generated by GAN network and high-resolution (HR) image is always unsatisfactory. In this paper, we propose a pixel-level self-paced adversarial network with multiple attention (PSPA) method to reduce the noise of SR image and increase its structural similarity with HR image. The combination of multiple attentions makes the model grasp the global information and restore the detail texture more accurately. The PSPA network can make the model notice the position with a large difference between the pixel values of SR and HR images and speed up the gradient descent speed. Our method shows excellent performance on Set5, Set14 and BSD100 datasets and overcomes many popular algorithms.
