Illumination invariant face recognition based on dual‐tree complex wavelet transform

This study presents a new dual‐tree complex wavelet transform (DT‐CWT)‐based illumination normalisation approach for face recognition under varying lighting conditions. The method consists of three steps. First, the DT‐CWT‐based edge detection method is proposed which can obtain estimation for facia...
