Effectiveness of Haar wavelet and grayscale features in different illumination for facial features detection

摘要

Wavelet is widely used in signal processing field. As the simplest wavelet framework, Haar wavelet is very popular dueto its memory efficient, fast and easy to implement. Haar wavelet can be employed to process the image for furtherpurpose like image compression. In this paper, the effectiveness of Haar wavelet and grayscale features are evaluated byemploying template matching as the principle technique. Results show that Haar wavelet feature is more relevant infacial feature detection task as compared to grayscale feature.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
