Abstract—Before designing a customized filter to improve the performance of homomorphic filtering technique on face images, the locations of illumination component in Fourier spectrum need to be identified. However, the background information of the face images available in the online database may affect the location of illumination component. Thus, a casing is designed to capture poorly illuminated face images with low contribution of reflectance components and dark background so that the exact location of illumination components can be identified accurately. This paper presents the specification of the casing and the light source circuit used to control the illumination on the face images.

Index Terms—homomorphic filtering technique, illumination, reflectance, casing, face images
