Cascaded generative adversarial network for panoramic image inpainting
摘要
Abstract
To address problems as the wide field of view and significant distortion in panoramic images,a panoramic image inpainting algorithm using a cascaded generative adversarial network is proposed in this paper.First,a dual-discriminator GAN is introduced to perform cubic projection transformations on equi-rectangular format panoramic images and restore the six faces of the cubic image.It incorporates a PatchGAN as the global discriminator to capture fine details,while a local discriminator network ensures the consistency of local restoration results with the surrounding areas.Then,a distortion-aware Generative Adversarial Network is introduced to mitigate distortion in panoramic images by using rectangular mixed convolutions.The discriminator employs spectral normalization and is cascaded with the first stage to mitigate issues of discontinuities at cubic image boundaries.A joint loss function is designed to optimize the network's restoration performance.Our experimental results demonstrate the proposed algorithm dilivers excellent performances in both subjective visual evaluation and objective assessment metrics,effectively restoring panoramic images.关键词
