Luxand FaceCrop SDK is face detection software that greatly optimizes and automates the process of creating professional-looking, passport-like photos from original images of any type.

With support for many different programming languages and formats, Luxand FaceCrop SDK is both versatile and effective, producing the highest quality images possible regardless of the quality and format of the original image.
