The characteristics of human body parts and behavior are measured with biometrics, which are used to authenticate a person. In this paper, the authors propose hybrid domain based face recognition using DWT, FFT and compressed CLBP. The face images are preprocessed to enhance sharpness of images using Discrete Wavelet Transform (DWT) and Laplacian filter. The Compound Local Binary Pattern (CLBP) is applied on sharpened preprocessed face image to compute magnitude and sign components. The histogram is applied on CLBP components to compress number of features. The Fast Fourier Transformation (FFT) is applied on preprocessed image and compute magnitudes.
