“…Recently, learning-based techniques such as deep convolutional neural networks (CNNs) and generative adversarial networks (GANs) have been widely used for a variety of image inpainting tasks, such as eliminating objects [7,8], noises [9], texts [10], and masks [11]. Usually, the proposed CNN-based methods are classified into three categories including coarse-to-fine, coarse-andfine, and structural guidance-based methods.…”
