Face Image Retrieval using Tchebichef Moments

Image Retrieval is a field of study concerned with searching and retrieving images from a collection of database. Face image retrieval is still a challenging task since face images can vary noticeably in terms of facial expressions, lighting conditions etc. In this paper we propose a face image retrieval method using Orthogonal Moments (Tchebichef Moment). This method extracts the feature from images by orthogonal moments to retrieve images from a large database. This method has been extensively assessed with YALE face database and FERET image Database. This method shows a noticeable performance compared to other methods.
