The images were captured in relatively controlled environments (similar lighting, backgrounds, and frontal poses). Modern deep learning often requires "in-the-wild" data to perform well in real-world scenarios where lighting conditions and camera angles vary drastically.

| Feature | Details | |---------|---------| | | ~55,000+ (commonly cited as 55,134) | | Unique subjects | ~13,000+ | | Age range | 16 to 77 years | | Time span | Up to ~10 years per individual (average ~2–3 images per person) | | Demographics | Approximately 77% African American, 23% Caucasian; gender distribution ~81% male, 19% female | | Image type | Mugshot-style, frontal faces with controlled lighting and neutral expression | | Annotation per image | Age, sex, race, date of collection, subject ID |

While newer, larger datasets scraped from the web (such as IMDB-WIKI or MegaAge) offer more images, MORPH II remains uniquely valuable due to its precise longitudinal tracking and verified ground truth metadata. It remains a foundational benchmark that every serious researcher in facial biometrics will encounter.

In addition to the widely used academic version, there is also a commercial version of the MORPH dataset. It is reportedly much larger, containing nearly 400,000 images of approximately 70,000 subjects, but is not available for general research purposes.

MORPH-II has been extensively utilized across a wide range of computer vision tasks, most notably:

Because the images are actual booking photographs, they contain natural variations: It remains a foundational benchmark that every serious

Standard bio‑inspired features (BIF) have achieved up to 98.5% accuracy on MORPH-II for gender classification.

The subjects range in age from 16 to 77 years , with an average age of approximately 33 years. The dataset has a heavily imbalanced demographic distribution:

The dataset (specifically the 2008 non-commercial release) contains roughly of approximately 13,000 unique individuals, taken between 2003 and 2007. Each image is accompanied by detailed metadata, including:
