Average Precision (AP) is defined and measured according to standard COCO evaluation procedure.
Image, name: image, shape: 1, 3, 480, 480 in the format 1, C, H, W, where:
C- number of channelsH- image heightW- image width
The expected channel order is BGR
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.
The OpenVINO Training Extensions provide a training pipeline, allowing to fine-tune the model on custom dataset.
The model can be used in the following demos provided by the Open Model Zoo to show its capabilities:
