Face detector for driver monitoring and similar scenarios. The network features a default MobileNet backbone that includes depth-wise convolutions to reduce the amount of computation for the 3x3 convolution block.

Average Precision (AP) is defined as an area under the precision/recall curve. Numbers are on Wider Face validation subset.
Name: input, shape: [1x3x384x672] - An input image in the format [BxCxHxW],
where:
- B - batch size
- C - number of channels
- H - image height
- W - image width
Expected color order is BGR.
The net outputs blob with shape: [1, 1, N, 7], where N is the number of detected
bounding boxes. The results are sorted by confidence in decreasing order. Each detection has the format
[image_id, label, conf, x_min, y_min, x_max, y_max], where:
image_id- ID of the image in the batchlabel- predicted class ID (1 - face)conf- confidence for the predicted class- (
x_min,y_min) - coordinates of the top left bounding box corner - (
x_max,y_max) - coordinates of the bottom right bounding box corner.
