Hello, I am doin a project on face detection+recognition. Face detection part is working properly. I hav done face recognition using PCA but this method is highly undependable, so i planned to use LDA once we get the weights using PCA. However LDA algo gives me a eigenvector of size m*m where m=number of classes(in my case faces). However for recognition testing the vector will be of size M*1. where M=no of eigen vectors using PCA and i hav to project it on the LDA space but the dimensions arent matching. so ther is an error. Please someone help me out. I am stuck at this point.
