Face Masks ensemble dataset is no longer limited to [Kaggle](https://www.kaggle.com/datasets/henrylydecker/face-masks), it is now coming to Huggingface!
|
11 |
|
12 |
+
This dataset was created to help train and/or fine tune models for detecting masked and un-masked faces.
|
13 |
|
14 |
+
I created a new face masks object detection dataset by compositing together three publically available face masks object detection datasets on Kaggle that used the YOLO annotation format.
|
15 |
+
To combine the datasets, I used Roboflow.
|
16 |
+
All three original datasets had different class dictionaries, so I recoded the classes into two classes: "Mask" and "No Mask".
|
17 |
+
One dataset included a class for incorrectly worn face masks, images with this class were removed from the dataset.
|
18 |
+
Approximately 50 images had corrupted annotations, so they were manually re-annotated in the Roboflow platform.
|
19 |
+
The final dataset includes 9,982 images, with 24,975 annotated instances.
|
20 |
+
Image resolution was on average 0.49 mp, with a median size of 750 x 600 pixels.
|
21 |
+
|
22 |
+
To improve model performance on out of sample data, I used 90 degree rotational augmentation.
|
23 |
+
This saved duplicate versions of each image for 90, 180, and 270 degree rotations.
|
24 |
+
I then split the data into 85% training, 10% validation, and 5% testing.
|
25 |
+
Images with classes that were removed from the dataset were removed, leaving 16,000 images in training, 1,900 in validation, and 1,000 in testing.
