Use Case and High-Level Description

This model is an instance segmentation network for 80 classes of objects. It is a Cascade mask R-CNN with ResNet101 backbone and deformable convolutions, FPN, RPN, detection and segmentation heads.

Example

Specification

Metric Value
COCO val2017 box AP (max short side 800, max long side 1344) 45.8%
COCO val2017 mask AP (max short side 800, max long side 1344) 39.7%
COCO val2017 box AP (max height 800, max width 1344) 43.55%
COCO val2017 mask AP (max height 800, max width 1344) 38.14%
Max objects to detect 100
GFlops 828.6324
MParams 101.236
Source framework PyTorch*

Average Precision (AP) is defined and measured according to standard COCO evaluation procedure.

Inputs

Image, name: image, shape: 1, 3, 800, 1344 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

  1. Name: labels, shape: 100 - Contiguous integer class ID for every detected object.
  2. Name: boxes, shape: 100, 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].
  3. Name: masks, shape: 100, 28, 28] - 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.
