2. ROI Align: Extracts features from proposals.

3. Mask Branch: Predicts object masks.

How Mask R-CNN Works:

1. Input: An image is fed into the model.

2. Feature Extraction: A backbone network extracts features.

3. RPN: Generates region proposals.

4. ROI Align: Extracts features from proposals.

5. Classification and Mask Prediction: Predicts object classes and masks.

Applications:

1. Object detection

2. Instance segmentation

3. Image analysis

Benefits:

1. High accuracy

2. Robust object detection and segmentation

Mask R-CNN is widely used in various applications, including computer vision, robotics, and medical imaging.
