Abstract:
The key point of face recognition is feature extraction, which was mainly described by a perfect lower dimensional feature space to image the high dimensional in the past, but recently, had been provided a new direction by the deep learning model. In this paper, a deep subspace model that under the Gabor feature descriptor modulation is put forward. The modulation based on a new type deep learning framework uses Gabor filter to process images, draws a multilayer network from the deep feature extraction built,gets the deep abstract feature modulated by the Gabor. Firstly, we compress the traditional 40 Gabor filters of 8 directions and 5 scales in scale into 8 basic Gabor filter banks; Then we put the description features filtered by Gabor into the deeply reformed subspace model separately to get the deep feature representation of the image; Secondly, deal these features with hash code, histogram block as the description features. We discuss the improvement of the face recognition by adding the deep multilayer subspace feature extraction modulation based on the FERET, ORL, CMU_PIE database. The results show that this algorithm could make a better discrimination, good robustness on the illumination, expression, and posture. Meanwhile, it also makes up for the shortcoming of the shallow layer network who easily affected by the training image.
