Dataset

Please, cite our paper if you use any this data!

• Lagenda dataset: images and annotation.

• IMDB-clean: follow these instructions to get images and download our annotations.

• UTK dataset: origin full images and our annotation: split from the article, random full split.

• Adience dataset: follow these instructions to get images and download our annotations.

  After downloading them, your data directory should look something like this:

  data
  └── Adience
      ├── annotations  (folder with our annotations)
      ├── aligned      (will not be used)
      ├── faces
      ├── fold_0_data.txt
      ├── fold_1_data.txt
      ├── fold_2_data.txt
      ├── fold_3_data.txt
      └── fold_4_data.txt

  We use coarse aligned images from faces/ dir.

  Using our detector we found a face bbox for each image (see tools/prepare_adience.py).

  This dataset has five folds. The performance metric is accuracy on five-fold cross validation.

  images before removal	fold 0	fold 1	fold 2	fold 3	fold 4
  19,370	4,484	3,730	3,894	3,446	3,816

  Not complete data

  only age not found	only gender not found	SUM
  40	1170	1,210 (6.2 %)

  Removed data

  failed to process image	age and gender not found	SUM
  0	708	708 (3.6 %)

  Genders

  female	male
  9,372	8,120

  Ages (8 classes) after mapping to not intersected ages intervals

• FairFace dataset: follow these instructions to get images and download our annotations.

  Click to expand!

  After downloading them, your data directory should look something like this:

  data
  └── FairFace
     ├── annotations  (folder with our annotations)
     ├── fairface-img-margin025-trainval   (will not be used)
         ├── train
         ├── val
     ├── fairface-img-margin125-trainval
         ├── train
         ├── val
     ├── fairface_label_train.csv
     ├── fairface_label_val.csv
  

  We use aligned images from fairface-img-margin125-trainval/ dir.

  Using our detector we found a face bbox for each image and added a person bbox if it was possible (see tools/prepare_fairface.py).

  This dataset has 2 splits: train and val. The performance metric is accuracy on validation.

  images train	images val
  86,744	10,954

  Genders for validation

  female	male
  5,162	5,792

  Ages for validation (9 classes):

  0-2	3-9	10-19	20-29	30-39	40-49	50-59	60-69	70+
  199	1,356	1,181	3,300	2,330	1,353	796	321	118
