question on pca based face recognition
显示 更早的评论
I have a questioner regarding PCA/Eigenface classifier,
1. Shall I calculate the eigen-vectors first in case of input images, then train the face matrix & then calculate the dist between test and train images for final classification?
OR
2.Shall I train the face matrix first & then calculate the eigenvectors then calculate the dist between test and train images for classifier?
Please reply & thanks in advance
