                1. Upload an image or choose an example.
                
                2. Choose the point label ('Add mask' means a positive point. 'Remove' Area means a negative point that is not segmented).
                
                3. Add points one by one on the image.
                
                4. Click the 'Segment with points prompt' button to get the segmentation results.
                
                **5. If you get Error, click the 'Clear points' button and try again may help.**
