人臉識別背后的數(shù)據(jù)清理問題研究
[Abstract]:Face recognition technology has made remarkable achievements with the rapid development of deep convolution neural network (deep convolution neural networks,DCNN). These results are mainly reflected in a deeper DCNN architecture and a larger training database. However, large databases (millions of levels) held by most private companies are not open to the public, even if the currently partially open large databases have too little information to guarantee accuracy and affect DCNN training. In this paper, an easy-to-use multi-angle image cleaning method is proposed to improve the accuracy of the data. The face detection algorithm is used to remove the image that can not detect the face, and the existing models are used to extract the image features from the cleaned data set. The similarity degree is calculated, and the number of dissimilar images between each image and other images in a human face image is calculated, and the data is cleaned according to the improved parameters. Experimental results show that the accuracy of the training model is improved on LFW and Youtube Face datasets, and 99.17% accuracy is achieved on LFW data sets using smaller data sets. The accuracy of Youtube Face data set is 93.53%.
