Dataset

• 16 images. 8 from my databases, and 8 from Flickr.

• Large ethnic, gender and age variety.

• 98 total faces. 66 “frontal” 32 profile.

Test

• The Viola Jones algorithm OpenCV implementation was used. (<2 sec per image).

• For Schneiderman Kanade, the www.pittpatt.com demo was used. (~10-15 seconds per image, including web transmission).

Results

• The Schneiderman-Kanade is very good and definitely out-performs Viola-Jones. (higher detection rate and lower FP simultaneously).
