Use Case and High-Level Description

This is a person detector that is based on MobileNetV2 backbone with ATSS head for 1280x720 resolution.

Example

Specification

Metric	Value
AP @ [ IoU=0.50:0.95 ]	0.444 (internal test set)
GFlops	24.7577
MParams	3.6302
Source framework	PyTorch*

Average Precision (AP) is defined as an area under the precision/recall curve.

Inputs

Image, name: input, shape: 1, 3, 720, 1280 in the format B, C, H, W, where:

• B - batch size
• C - number of channels
• H - image height
• W - image width

Expected color order is BGR.

Outputs

1. The boxes is a blob with the shape 100, 5 in the format N, 5, where N is the number of detected bounding boxes. For each detection, the description has the format: [x_min, y_min, x_max, y_max, conf], where:

   • (x_min, y_min) - coordinates of the top left bounding box corner
   • (x_max, y_max) - coordinates of the bottom right bounding box corner.
   • conf - confidence for the predicted class

2. The labels is a blob with the shape 100 in the format N, where N is the number of detected bounding boxes. In case of person detection, it is equal to 1 for each detected box with person in it and 0 for the background.
