ABSTRACT: Face recognition is an
active area of biometrics. This study investigates the use of Chain Codes as
features for recognition purpose. Firstly a segmentation method, based on skin
color model was applied, followed by contour detection, then the chain codes of
the contours were determined. The first difference of chain codes were
calculated since the latter is invariant to rotation. The features were
calculated and stored in a matrix. Experiments were performed using the University of Essex Face database, and results show a
recognition rate of 95% with this method, when compared with Principal
Components Analysis (PCA) giving 87.5% recognition rate.
