Face recognition method and system based on super-resolution and feature whitening technology

The invention provides a face recognition method and system based on super-resolution and feature whitening technologies. The method comprises the following steps: acquiring a picture to be subjected to face recognition; performing super-resolution processing on the obtained picture to obtain a reconstructed high-resolution picture; carrying out face feature extraction on the reconstructed high-resolution picture; carrying out PCA dimension reduction on the extracted features; carrying out whitening processing on the dimension-reduced features; and inputting the whitened features into a face recognition model to perform face recognition. 本发明提供了一种基于超分辨和特征白化技术的人脸识别方法和系统。方法包括：获取待进行人脸识别的图片；对获取的图片进行超分辨处理以得到经重建的高分辨率图片；对经重建的高分辨率图片进行人脸特征提取；对提取的特征进行进入PCA降维；对经降维的特征进行白化处理；以及将经白化的特征输入人脸识别模型，进行人脸识别。
