DEVICE AND METHOD OF FACE IMAGE RECONSTRUCTION USING FREQUENCY COMPONENTS AND SEGMENTATION

摘要

The present invention provides a method for separating a frequency component from collected sample face images, dividing the frequency component into a plurality of regions, extracting image patches from the regions and restoring a high-resolution face image using the image patches according to the input of face image which is subject to restore. As an embodiment of the present invention, a low-resolution face image restoration device includes: a frequency component identification unit for separating a high-frequency component and a low-frequency component from a sample face image; a region division unit for dividing each the low-frequency component and high-frequency component into a plurality of regions; an image patch extraction unit for extracting a low-frequency image patch related to the low-frequency component and a high-frequency image patch related to the high-frequency component in the regions; and an image restoration unit for restoring the first component separated from a restoration target face image into a second component using the low-frequency image patch and high-frequency image patch.
