Procedure 1 Testing recognition with cropped class images

Elgenfaces created from class images (non_smiling)

10 Elgenfaces

Average Face

When the number of eigenfaces is below 21, more faces will be recognized when the eigenfaces number increases. When the eigenface number is equal to or greater than 21, the number of recognized face is fixed even though the eigenface number is getting bigger. Therefore, more eigenfaces do not mean a better face recognition.

10 or 11 eigenfaces should be reasonable values.

Faces mismatched (a couple of samples)

Procedure 2: Cropping and finding faces

parameters: min_scale = 0.45, max_scale = 0.55, step = 0.01

parameters: min_scale = 1, max_scale = 1.1, step = 0.1

paramparameters: min_scale = 1, max_scale = 1.1, step = 0.1

paramparameters: min_scale = 0.9, max_scale = 1.1, step = 0.1
