Reference work entry
DOI: https://doi.org/10.1007/978-0-387-73003-5_1067

Finding significant features in images such as landmarks, edges, or curves. For example, a facial feature detector aims to find the positions of the center of an eye, the corners of a mouth, or the top of a nose in a face image. In the case of an iris image, features may mean the edges inside an iris or the boundaries around the iris.
