METHOD AND SYSTEM FOR HIGH-RESOLUTION IMAGE INPAINTING

摘要

Methods (800) and systems (105) for high-resolution image inpainting are disclosed. An original high-resolution image to be inpainted is obtained, as well as an inpainting mask indicating an inside-mask area to be inpainted (802). The original high-resolution image is down-sampled to obtain a low-resolution image to be inpainted(804). Using a trained inpainting generator (101), a low-resolution inpainted image and a set of attention scores are generated from the low-resolution image (806). The attention scores represent the similarity between inside-mask regions and outside-mask regions. A high-frequency residual image is computed from the original high-resolution image(808). An aggregated high-frequency residual image is generated using the attention scores, including high-frequency residual information for the inside-mask area (810). A high-resolution inpainted image is outputted by combining the aggregated high-frequency residual image and a low-frequency inpainted image generated from the low-resolution inpainted image (812,814).
