I am doing face recognition using pca. I want to train images of 40 people. So is it mandatory to give same number of images of each person at the time of training or I can give different number of images ?. Is there any change in the recognition result when I give same number of images and different number of images of each person?
No, when using it for the training stage, PCA does not require to give the same number of images for each person. Thus, you can use the different numbers of training images associated with training objects. And if you use the same number of images and different number of images for each person, the recognition rate changes because each image of one person contributes different amount of discriminative features to construct the eigenvectors. But one thing you can be sure is that: the more images you use for training, the better recognition rate you will achieve.
no, you do not need exactly the same image count per person.
you do need enough images per person, though. (like a good dozen or two)
