Image Inpainting with a Three-Stage Generative Network

One of the research emphases of image inpainting based on deep learning is to generate color, edge and texture. However, generation methods of these three important properties need to be further improved. A three-stage generative network is proposed, and three stages tend to synthesize colors, edges and textures respectively. Specifically, the global color of the image is reconstructed in the HSV color space at the HSV color generation stage to provide color guidance for image inpainting. An edge learning framework is designed at the edge optimization stage to obtain more accurate edge information. At the texture synthesis stage, a decoder with feature bidirectional fusion is designed to enhance the details of the image. The three stages are successively connected, and each stage plays an important role in improving the performance of image inpainting. Extensive experiments demonstrate the superiority of the proposed method compared with the state-of-the-art methods. © 2022 Journal of Pattern Recognition and Artificial Intelligence.
