instance-segmentation-security-1039¶
Use Case and High-Level Description¶
This model is an instance segmentation network for 80 classes of objects. It is a Mask R-CNN with EfficientNet-B2 backbone, light-weight FPN, RPN, detection and segmentation heads.
Example¶

Specification¶
| Metric | Value | 
|---|---|
| COCO val2017 box AP | 32.9% | 
| COCO val2017 mask AP | 28.6% | 
| Max objects to detect | 100 | 
| GFlops | 13.9672 | 
| MParams | 10.5674 | 
| Source framework | PyTorch* | 
Average Precision (AP) is defined and measured according to standard COCO evaluation procedure.
Inputs¶
Image, name: image, shape: 1, 3, 480, 480 in the format 1, C, H, W, where:
- C- number of channels
- H- image height
- W- image width
The expected channel order is BGR
Outputs¶
Model has outputs with dynamic shapes.
- Name: - labels, shape:- -1- Contiguous integer class ID for every detected object.
- Name: - boxes, shape:- -1, 5- Bounding boxes around every detected objects in (top_left_x, top_left_y, bottom_right_x, bottom_right_y) format and its confidence score in range [0, 1].
- Name: - masks, shape:- -1, 14, 14- Segmentation heatmaps for every output bounding box.
Training Pipeline¶
The OpenVINO Training Extensions provide a training pipeline, allowing to fine-tune the model on custom dataset.
Demo usage¶
The model can be used in the following demos provided by the Open Model Zoo to show its capabilities:
