Wavelet is widely used in signal processing field. As the simplest wavelet framework, Haar wavelet is very popular due to its memory efficient, fast and easy to implement. Haar wavelet can be employed to process the image for further purpose like image compression. In this paper, the effectiveness of Haar wavelet and grayscale features are evaluated by employing template matching as the principle technique. Results show that Haar wavelet feature is more relevant in facial feature detection task as compared to grayscale feature.
