自然场景中小样本人脸图像修复对人脸识别的影响
The Influence of Image Restoration of Small Face Sample in Natural Scenes on Face Recognition
摘要
Abstract
Objective The aim is to investigate the impact of the quality and image restoration methods of small face sample on the performance of facial recognition systems,in order to improve the effectiveness of forensic appraisal recognition.Methods This paper focused on the impact of few-shot face image inpainting on face recognition technology in natural scenes.We selected few-shot face images from the Labeled Faces in the Wild database.Then,we used Gaussian filtering technology on these images.This simulated the quality of real-life blurred face images.At the same time,different face image inpainting methods based on deep neural networks were used to repair the blurred face images.The influence of different few-shot face images quality and different inpainting methods on the recognition performance of face recognition was studied by statistical analysis.Results The face image inpainting technology enhanced the clarity of small face image samples.Moreover,the technology boosted the visual recognition of identity information in these images.However,the repaired face images negatively affected face recognition.Conclusion Face image inpainting technology plays a positive role in portrait identification,but it should be used more carefully when be applied in face recognition.关键词
