Face Place
For the final installation, I'm going to use the database from Face Place (a database of human faces by race and gender) but recreate it.
To make the result more accurate, I had done some tests with the Eigenface programme.
Here are some images from the database I used for the test, all the photos have the same background color and also the same dimension(280*200). Then I added a new face (Taylor Swift), with a black background and larger dimension, into this database. After I ran the programme, the new face can barely be analysis by the application as the image below show.

Then I changed the background color and dimension of the new face with Preview (same as the other faces), and the result is totally different:
As the image below shown, I then compared another image (changed to green background) of Taylor Swift in different hairstyle and mack-up, although the distance is big, it still got the correct result.
To get a more accurate result with the Eigenface, the faces inside the database must have:
- same face size
- same image dimension
- same background colour
