Document Type and Number:
WIPO Patent Application WO/2021/246821
Kind Code:
A1
Abstract:
Provided in the present embodiment are a method and a device for restoring a facial image, the method and the device: detecting the positions of landmarks on the face in a bounding box detected from an input image; improving the image by using a learning model trained with a front facial image in a state of having performed warping, which aligns the front of the face so that same is positioned in the center or at a reference position on the basis of the landmarks; and performing inverse warping for rotating the improved image to the original direction or angle again, and then inserting same into the input image so that a more natural image can be obtained through restoration. In addition, provided in the present embodiment is a method and a device for restoring a facial image, the method and the device estimating the pose of the face in a bounding box detected from an input image, and improving an image by using a learning model trained with a side facial image corresponding to the pose estimation result.
