Face recognition is very important for many applications such as: video surveillance, criminal investigations and forensic applications, secure electronic banking, mobile phones, credit cards, secure access to buildings. The curvelet transform is a multi scale directional trans-form, which allows an almost optimal non adaptive sparse representation of objects with edges.
