Embodiment Construction
[0039] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0040] figure 1 The flow chart of the robust face recognition method based on image sparse representation proposed by the present invention, combined with figure 1 The implementation process of the present invention is described in detail:
[0041] Step S1, face image preprocessing;
[0042] Grayscale and scale normalization preprocessing is performed on the face images in the face database, and all images are normalized to a size of 32×32 pixels.
[0043] Step S2, feature extraction of multi-directional Gabor feature maps;
[0044] The present invention adopts the feature extraction method of multi-directional Gabor feature map (Multi-directional Gabor Feature Maps, MGFM), such as figure 2 As shown in Fig. 1, the face image is first subjected to multi-directional and multi-scale Gabor transformation, and then the Gabor f...
