Web4.2. Step 2: Expanding the face class in the LDA space To expand the region for each subject, a set of face images can be randomly selected from that subject’s video, a high-dimensional feature vector can be generated for each of these face images. These vectors can then be projected onto the lower dimensional WebThus the projection of vector b onto the column space of A is bp = (bTq1)q1 +(bTq2)q2 bp = 6 p 24 q1 + 4 p 32 q2 = 6 24 2 4 2 4 ¡2 3 5+ 4 32 2 4 4 0 4 3 5 bp = 2 4 1 1 0 3 5 2 Second …
