The ( Craniofacial Longitudinal Morphological Face Database ) is one of the most widely cited and utilized longitudinal facial image databases in computer vision. Created by the Face Aging Group at the University of North Carolina at Wilmington (UNCW) under the direction of Dr. Karl Ricanek, it was designed to assist researchers in studying face aging, age estimation, face recognition, and demographic classification. | Strengths | Limitations | | :--- |

The MORPH II dataset offers several benefits, including:
As of 2023-2025, the original hosting at UNCW has become less active, and the dataset is most reliably accessed via the National Institute of Standards and Technology (NIST) and face recognition research communities.
Machine learning models use MORPH II to predict a subject's chronological age from a single static image. Because the dataset contains exact age labels, it serves as the primary training and testing ground for Mean Absolute Error (MAE) benchmarks in regression models. 2.
