Overview

B3FD (Biometrically Filtered Famous Figure Dataset) is a publicly available, unconstrained facial image dataset for age estimation. It is derived from the IMDB-WIKI and CACD datasets and automatically cleaned using unsupervised biometric filtering methods to remove faulty web-scraped samples.

• Total images: 375,592 facial samples
• Unique subjects: 53,759 (≈ 6.99 images per subject)
• Age range: 0–100 years
• Primary use: Facial age (and partially gender) estimation
• Intended use: Academic research

Features

• Biometric filtering and cleaning

  • Derived from IMDB-WIKI and CACD facial datasets.
  • Unsupervised biometric filtering used to remove erroneous or noisy web-scraped samples.
  • Removal rates:
    • IMDB-WIKI: 53% of samples removed.
    • CACD: 20% of samples removed.

• Dataset composition

  • Total images: 375,592.
  • Total unique subjects: 53,759.
  • Average samples per subject: 6.99.
  • Age labels from 0 to 100.

• Subsets

  • B3FD-IWS (IMDB-WIKI subset)
    • 245,204 processed samples.
    • 53,568 unique subjects.
    • ≈ 4.58 samples per subject.
  • B3FD-CS (CACD subset)
    • 130,388 processed samples.
    • 1,831 unique subjects.
    • ≈ 71.21 samples per subject.
  • Subsets intended for scenarios with data-origin constraints (e.g., only IMDB-WIKI- or CACD-derived data).

• Image properties

  • All images are pre-aligned.
  • Cropped with 50% context around the face.
  • Resized to 256×256 pixels.

• Metadata

  • Main metadata file: B3FD_metadata/B3FD_age.csv
    • Contains pairs of image paths and age labels for the full dataset.
  • Subset metadata files:
    • B3FD_metadata/B3FD-IWS_age.csv (IMDB-WIKI-derived subset) – image path + age.
    • B3FD_metadata/B3FD-CS_age.csv (CACD-derived subset) – image path + age.
  • Additional age + gender metadata (IMDB-WIKI-origin samples):
    • B3FD_metadata/B3FD-IMDB_age_gender.csv
    • B3FD_metadata/B3FD-WIKI_age_gender.csv

• Filtration lists

  • Provided under B3FD_filtration_lists archive.
  • Can be used if you wish to re-apply or adjust image processing with your own pipeline while preserving the same filtered sample selection.

• Performance context

  • According to the accompanying paper, B3FD data is shown to outperform other evaluated publicly available age estimation datasets (details in the referenced publication).
